1 Copyright

You are allowed to copy and spread this program but only if you do not make any commercial profit out of the program itself and all supported files. The source of MUIProCalc is considered teachware and the author claims the right to be the only one to produce and release new versions of MUIProCalc. Public Domain vendors are not allowed to sell MUIProCalc for more than the price of a regular disk, which should not be higher than 5 Dollars.

MUIProCalc is GiftWare, so if you like it and you you want to express your feelings, feel free to send me anything you think of being suited. Postcards, cookies, money, simply anything ;)

2 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.

3 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.

4 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© 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

5 Using MUIProCalc

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

Within the window‘s titlebar you‘ll see the currently selected output modes.
The first char is for base, the second for size, the third for sign and the
fourth entry is for angle settings.

5.1 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 section History settings, to find out more about history settings.

5.2 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 section Window layout, to find out more about that.

5.3 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 section Window layout, to find out more about that.

5.4 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

5.5 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.

5.6 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.

5.7 The menus

MUIProCalc offers a set of menus. These are :

5.7.1 Project

The Project menu offers three entries :

‘Preferences...’

Will open the Preferences editor (see section Preferences)

‘About...’

Will display about messages

‘Quit’

Will quit MUIProCalc

5.7.2 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 section Preferences).

‘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 section Preferences).

‘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 section Preferences).

‘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 section Preferences).

‘Delete entry’

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

5.7.3 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 section Sign).

The default output type may be set using Output settings.

5.7.4 Size

For the ’Hexadecimal’, ’Octal’, and ’Binary’ modes (see section Display 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 settings.

5.7.5 Sign

For ’Decimal’ output (see section Display 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 settings.

5.7.6 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 settings.

5.7.7 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.

5.8 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.

6 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.

6.1 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.

6.2 Output settings

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

See Display Bases Size Sign Angle

6.3 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.

6.4 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.
