   Welcome to MUIProCalc v1.5. This is a short description on how to use
MUIProCalc and what possibilities it offers. Anyway, it is a quite
powerful calculator, also suited for programmers who have to deal with
different computer specific calculations and values.

   MUIProCalc doesn`t stand for MUI'Professional'Calc. It is meant to
stand for MUI'Programmer'Calc...

MUIProCalc (MCalc) is (C) 1993 Kai Iske, GiftWare

   The icon for MUIProCalc was taken from the ToolManager 2.0
distribution and was designed by Michael 'Mick' Hohmann.

Guarantee
*********

   The author does not give any guarantee that the program MUIProCalc
works perfectly.  The program was tested and it is used every day,
anyway nobody is perfect and that is why I can not take the
responsibilty for any damages occured during the usage of MUIProCalc.

Evolution
*********

   Due to the fact that I was still using Calc 3.0, written by Jimmy
Yang, which wasn`t that compatible to newer Kickstarts, I thought about
writing a new one, since I couldn`t find any calculator suited my
needs. Not that Calc 3.0 was/is buggy, but it`s just the fact that it
isn`t font adaptive. Furthermore I wanted to know how powerful MUI
really was, so I thought it`d be a good idea to write it using MUI.

   Taking Calc 3.0, I tried to implement the functionality of this
calculator, putting it into a MUI-GUI. What is still missing is the
plotter. This may change in a later release.

   One word to the parser: The grammar might not be perfect. There`s
only a small amout of syntax checking, in order to minimize parser
size. Float value error handling isn`t perfect either, yet. I just
wanted to have a calculator as soon as possible. All this will change
in future releases, if there are enough of replies.

Installing MUIProCalc
*********************

   Installing MUIProCalc isn`t that hard. First of all you should get
hold of MUI (MagicUserInteface) and install it. MUIProCalc relies on
MUI, since the complete User Interface was written using this great
system.

   Having installed MUI (if you haven`t done so already), you may copy
the program MCalc and it`s icon MCalc.info to a place you like.

   If you want to use the online help, you have to have AmigaGuide(C)
installed. If so, move the supplied MCalc.guide file to the same
directory you moved the main program to.

   That`s it. In order to get online help, simply position the mouse
over the object you want to get help for and MUIProCalc will pop up a
window containing the help text.

   One word to the menu shortcuts : They might not be Style Guide
compliant, but I think it`ll work just fine, anyway ;)

       NOTE that you better set the stack size to at least 8192 bytes

Using MUIProCalc
****************

   Well, it isn`t that hard to use MUIProCalc. The main input window is
devided into three areas, which are

The input/output area
=====================

   Within this area (the upper) you see a String gadget and a ListView
gadget.  The String gadget is used to enter the expressions you want to
calculate.

   Within the ListView you see a history of all entered expressions and
results. Per default the left column of the ListView is used to display
the expression, whilst the right one reflects the result. You may set
the number of lines bufferd using the Preferences. Furthermore you may
tell MUIProCalc how to format the entry, i.e. you may have four
different output types.  See History, to find out more about history
settings.

Function tables
===============

   Within this area you`ll find all the functions supported by
MUIProCalc.  Simply click on the function you want to be added to the
expression.  Depending on your MUI Preferences you, will either see a
Cycle gadget, or a set of registers. Using either of those, you may
switch between five function tables. The first set is a more
mathematical set, whilst the second might only be of use to
programmers. There are functions for bit-manipulation etc.pp. The third
contains a set of memories, you may store temporary results in. Thr
fourth and the fifth are for standard deviation and linear regression
calculations respectively.

   This Group may be hidden, thus leading to more space. See Layout, to
find out more about that.

Input fields
============

   These are buttons probably known from any other calculator. Simply
click on the digit/operator you want to add to your expression. The
characters 'A-F' are used to enter hexadecimal values. The other
characters 'I-Z' are memories. These can be set using an expression of
the form

                            x = sqrt (2*3)

   This expression will set memory 'X' to the result of 'sqrt (2*3)'.
You may now use this value during other operations. You may even set a
memory relative to another one, like

                          x = y + sqrt (2*3)

   MUIProCalc supports four different value formats, these are :

Decimal
     Decimal values are entered with no additional characters, like
     '2.12322'.  You may even enter doubles using scientific notation,
     like '2.123e-2'

Hexadecimal
     These values are preceded by a '$'-sign or by '0x'

Octal
     These values are preceded by a '\'-sign

Binary
     These values are preceded by a '%'-sign

   The '!' operator is used to calculate the factorial of a value. This
one is limited to a value of !170.

   The 'Exec' button may be used to 'start' the calculator. This can
also be done, by simply hittin RETURN from within the String gadget

   For percentage calculations there are several modes and functions:

   * X + Y%

     Will add Y% of X to X

   * X - Y%

     Will subtract Y% of X from X

   * X * Y%

     Will calculate the Y percentage of X

   * X %ch Y

     Will return the percentual changes between X and Y

   * X %t Y

     Y is which percentage of X? Eg. 250 %t 10 will return 4.

   Here is a list of functions, you probably can`t make anything out
of, on first sight:

   * (n k)

     Usage in calucaltor: n_expression '(n k)' k_expression. This will
     calculate the expression 'n over k' (N!/(N-K)!)

   * YRoot

     Usage in calculator: y_root 'YRoot' x_value. This will calculate
     the yth root of x.

   * REZ

     Usage in calculator: 'REZ' x_value. This will calculate the
     reciprocal of x.

   * EXG

     Usage in calculator: mem_1 'EXG' mem_2. This function will swap
     contents of the specifed memories (mem_1 and mem_2)

   'CLR' clears the current display.

   'ACLR' will clear the display and all memories plus standard
deviation values and linear regression value pairs.

   This Group may be hidden, thus leading to more space. See Layout, to
find out more about that.

Calculating standard deviation
==============================

   For calculating statistical functions, such a the standard deviation
or the linear regression, MUIProCalc offers a somewhat different
approach for entering the values. I will now explain the actions you
have to take, in order to calculate standard deviation for a set of
values.

   First, you have to initialize the list of values, this is accomlished
through the SD command. It expects, enclosed in brackets, a list of
values, each seperated by a comma.

                       SD(120, 145, 80, 65, 120)

   Would set up five values for standard deviation calculations. You
may enter expressions for each value, like '120*2/X', of course.

   Now, according to the values entered, MUIProCalc offers functions for
calculation, which are:

SD_AVE
     This function will return the average value of the values entered.

SD_PDEV
     Will calculate the standard deviation of the population for the
     values entered.

SD_SDEV
     Will calculate the standard deviation of the sample for the list
     of values entered.

SD_QSUM
     Will return the sum of all values, each value powered by 2, ie.
     SIGMA X^2

SD_SUM
     Will return the sum of all values, ie. SIGMA X

SD_NUM
     Will return the number of elements in the list

Calculating linear regression
=============================

   This set of functions is nearly the same as the one described for
standard deviation. Again you first have to enter some values, this
time pairs of values, for the calculator to work with. As linear
regression works with pairs of values, you somehow have to bring two
values into some sort of relationship. This is accomplished, for
example, by:

            LR(10;1003, 15;1005, 20;1010, 25;1011, 30;1014)

   This will set up a list of pairs of values. This list of X values
will be set to 10, 15, 20, 25, and 30, while the list of Y values will
be set to 1003, 1005, 1010, 1011, 1014. As you can see, a pair is set
up by the X value, followed by a semicolon and the Y value. Each pair
is, again, seperated through a comma.

   Here is a list of functions to work with linear regression:

LR_XAVE, LR_YAVE
     Will return the average value for the X or Y values respectively

LR_XPDEV, LR_YPDEV
     Will return the standard deviation of the population for either
     the X values, or the Y values

LR_XSDEV, LR_YSDEV
     Will calculate the standard deviation of the sample for either the
     X values, or the Y values

LR_XNUM, LR_YNUM
     This function either returns the number of X values, or the number
     of Y values. Of course, these numbers will always be the same ;)

LR_XQSUM, LR_YQSUM
     Will calculate the sum of X values, or Y values powered by 2, ie.
     SIGMA X^2 or SIGMA Y^2

LR_XSUM, LR_YSUM
     Will return the sum of X values, Y values

LR_XYSUM
     Will return the sum of the products of each X,Y value pair, ie.
     SIGMA (X*Y)

LR_ALPHA
     Will calculate the alpha part of the formula of regression (y =
     alpha + beta * x)

LR_BETA
     Will calculate the beta part of the formula of regression (y =
     alpha + beta * x)

LR_ASSX <expr>
     Given a fixed value or an expression for the Y value, this
     function will try to assess the value of the X value

LR_ASSY <expr>
     Given a fixed value or an expression for the X value, this
     function will try to assess the value of the Y value

LR_CORR
     Will return the correlation coefficient for the linear regression
     (r)

LR_CCORR
     Will return the critical correlation coefficient for the linear
     regression (r^2)

LR_COVAR
     Will return the covariant for the linear regression.

Some special notes on usage
===========================

   MUIProCalc doesn`t really act like a real calculator, you probably
own. For example, if you like to calculate the square root of 9^3, you
usally follow these steps to calculate it with your calculator:

Enter 9
Press your 'x powered by y' key (x^y)
Enter 3
(Hit your '=' key), which depends on which calculator you use
Hit your square root key
     You get the result (27)

   With MUIProCalc you take a different approach. This is almost the
same as when writing the formula down a sheet of paper. Usually you
would write 'sqrt (9^3)' or 'sqrt 9^3'. This is the same with
MUIProCalc: You enter this formula into the Input gadget and simply hit
the Exec gadget or hit the RETURN key.  MUIProCalc will now return the
result (again 27; well, how come?). As you can see, this is somewhat
different to normal or rpn calculators. You enter the formula as if you
wrote it down, and let MUIProCalc parse and evaluate the expression.

The menus
=========

   MUIProCalc offers a set of menus. These are :

Project
-------

   The Project menu offers three entries :

Preferences...
     Will open the Preferences editor (see Prefs)

About...
     Will display about messages

Quit
     Will quit MUIProCalc

History
-------

   If you prefer to use your mouse or the menu shortcuts you may paste
an entry from the history to the current cursor position from within
this menu :

Pick left entry
     Will pick the left entry from the list and paste it to the current
     cursor position. If only one column is shown, this will be used
     (see Prefs).

Pick right entry
     Will pick the right entry from the list and paste it to the
     current cursor position. If only one column is shown, this will be
     used (see Prefs).

Copy left entry
     Selecting this item will copy the left entry from the history to
     the selected clipboard unit. If only one column is show, this one
     will be used (see Prefs).

Copy right entry
     Selecting this item will copy the right entry from the history to
     the selected clipboard unit. If only one column is show, this one
     will be used (see Prefs).

Delete entry
     This menu item will cause MUIProCalc to delete the selected entry
     from the history.

Display Bases
-------------

   This menu may be used to set the display mode for output. You may
have 'Decimal', 'Hexadecimal', 'Octal', or 'Binary' output.

   In any other mode than 'Decimal' there will be no difference between
'Signed' and 'Unsigned' modes (see Sign).

   The default output type may be set using Output.

Size
----

   For the 'Hexadecimal', 'Octal', and 'Binary' modes (see Bases), you
may set an output value size (number of bits).  This will
reduce/increase maximum numbers.

   The default output type may be set using Output.

Sign
----

   For 'Decimal' output (see Bases), you may have signed or unsigned
results, when you enter 'Hexadecimal', 'Octal', or 'Binary' values.

   The default output type may be set using Output.

Angle
-----

   For trigonometrical functions you may set the type of angle you`ve
entered.  If you set 'RAD', the values will be interpreted as of type
radians, if you set 'DEG' angles will be interpreted as of type
degree. Finally there is type 'GRA' so that angles are interpreted as
of type grads.

   The default output type may be set using Output.

Windows
-------

   Within this menu you will find three entries, each of which will
open a support window:

Std.Deviation
     This one will open the support window for standard deviation.
     Within the window you will find a list of all values entered for
     standard deviation.  This is just for validation checks, in order
     to see, whether you`ve entered correct values. Basically it`s of
     no use for calculation.

Lin.Regression
     Same as for the Std.Deviation window. Within this window you will
     find the list of pairs of values entered for linear regression.
     Again, this is just for validation.

Constants
     This is a more useful window. It will list 31 constants, useful for
     Physicians, or anyone else who is calculating with one of the well
     known constants. If you never ever had the nerve to learn all
     those constants by heart, here they are (well, I guess not all).
     Simply double click on an entry within the list, and the value
     will be copied to the Input gadget.

The ARexx Port
==============

   In addition to the default ARexx commands every MUI application
knows about, MUIProCalc offers some more, these are :

   As with every MUI Application the name of the ARexx Port is
constructed from the base name of the Application. For MUIProCalc this
will be 'MCALC'.

   BTW: If you read something about TeX compatible output, this means
you may use these strings directly within a mathematical environment.
The current conversion routine isn`t quite intelligent I have to admit.
Maybe I`ll add a smarter one for the next release...

   There are two scripts included for use with CygnusED which
demonstrate how to use the ARexx Port.

Preferences
***********

   Within the Preferences window you may configure some of MUIProCalc`s
default values. These are :

   Furthermore the active function table, set with the 'Functions'
cycle gadget within the main window, will be taken into account.

Use
     will use the current settings and store them temporarily, so if you
     restart MUIProCalc, these settings will be used again.

Save
     will save/store the settings on disk.

Cancel
     will restore the previously used values.

Window layout
=============

   Within this group there are two CheckBox gadgets. if the 'No
Functions' CheckBox is set, the main window will not contain the
function tables. If not the function tables will be displayed. If you
set 'No Input' the input fields will not be displayed. If you clear
this CheckBox, the lower gadget group will be displayed.

   Using the 'In/Out Order' gadget you may control the ordering of the
input String gadget and the output ListView gadget. When 'Input then
Output' is selected, the String gadget will appear 'on top' of the
ListView. Otherwise ('Output then Input') it will appear underneath the
ListView.

Output settings
===============

   You may set the default values for 'Display Bases', 'Size', 'Sign'
and 'Angle' here.

   See Bases Size Sign Angle

History settings
================

   Using the 'Lines' Slider gadget you may adjust the maximum number of
lines to capture during a session.

   With the 'Entries' Cycle gadget you may set the output format for
the history.  You may choose from the following formats :

Input & Ouput
     Within the left column you`ll see the expression entered. In the
     right column there`ll be the result for that expression.

Output & Input
     Is the opposite to the above

Input
     Will only show your input expression

Output
     Will only show the result

   Using the 'ClipUnit' Slider gadget you may set the default
clipboard unit for History clipping. Simply select a unit you want to
use.

Misc
====

   Set the 'Clear input on exit' CheckBox gadget if you prefer to have
the input gadget cleared every time you`ve entered an expression.
Otherwise simply clear it.

   The 'Flush memory' CheckBox gadget may be used to tell MUIProCalc to
flush all unused libraries (including unused MUI-Classes) from memory
on exit, thus freeing all that precious memory used up by MUIProCalc.

   The 'Deviation window', 'Regression window' and 'Constants
window' tell MUIProCalc whether to open the corresponding windows, or
not ('Std.Deviation', 'Lin.Regression' and 'Constants' windows). Set a
CheckBox gadget in order to make MUIProCalc open that window on startup.
