- MathU Pro 1.4 Readme
- ====================
-
-
- What is MathU Pro?
- ------------------
- MathU Pro is a programmable Reverse Polish Notation (RPN) scientific and
- financial calculator for the Palm Computing¿ platform. It is based on the
- popular MathU calculator and supports double precision accuracy, 112
- built-in functions including 5 financial functions, and has 1044 memory
- registers (20 are global and 1024 are local to each program). Programs are
- written in a keystroke-like language using the included editor. Assign your
- program to any key on the keyboard. Quickly switch between programs via a
- pop-up menu on the main screen. Beam your programs to friends.
-
- Comes bundled with two example function sets: A units conversion
- set and an alternative keyboard layout with a few new functions (like
- R->P and H.MS conversions).
-
- What is new in Version 1.4?
- ---------------------------
- Version 1.4 adds
-
- o Preference added to accumulate the sum of x*y in register 9.
- o New CHOP opcode. Rounds a number to match the value displayed.
- o New SECONDS opcode. Returns the number of seconds since 1/1/1904
- o Increased the length of the PAUSE to 2 seconds.
- o Documentation is improved.
- o Bugs fixed:
- - The INT and FRAC functions now chop to nine digits of precision before
- computing their results. FLOOR, CEIL, and ROUND continue to work as before.
- - Editing a CONST string could crash MathU Pro.
-
- Version 1.3 added
-
- o Program indenting
- o Palm OS 3.5 compatibility
- o Bugs fixed:
- - CLRVARS function could crash MathU Pro if no variables existed.
- - B/E key on main keyboard wasn't always toggling the annuity mode.
-
- Version 1.2 added
-
- o MathU Pro Editor is now a separate application. The editor requires MathU
- Pro but you can delete it to save 37K on your Palm device.
- MathU Pro will run programs but cannot edit them if the editor is not
- installed.
-
- o Beam your programs to friends. Sharing your MathU Pro programs is now as
- easy as selecting "Beam Program" from a menu.
-
- o Local registers. MathU Pro programs now support up to 1024 local registers.
- These registers are persistent and are transferred with your program during
- a Hot Sync or when a program is beamed.
-
- o Indirect store and recall. Programmatically access the contents of a
- register. Easily step through a range of registers.
-
- o Easy duplication of a program or program steps. Just select the "Dup"
- button in the list or edit screens.
-
- o Built-in quick reference. Get quick help without having to consult the
- documentation.
-
- o Bugs fixed:
-
- - The MOD function now correctly sets the LastX register.
-
- - DECR and INCR now perform any actions when the value in the register
- crosses zero. It used to perform the action only when the value exactly
- equaled zero.
-
- - The Palm device is now prevented from going to sleep while a program is
- running.
-
- Version 1.1 added
-
- o Support for the special MathU symbols shown on the keyboard. Now you can
- include these characters in your button labels and SHOW strings.
-
- o Support for NOT tests in IF conditions.
-
- o Support for STO +, STO -, STO *, STO / via the keyboard.
-
- o New PROMPT function. This function displays the prompt string specified in
- a dialog and waits for user input. Useful for gathering parameter values in
- your programs.
-
- Version 1.0 and 1.1 Function Sets are supported. They will be converted to version
- 1.2 function sets after editing. Version 1.2 function sets will not work
- with MathU Pro 1.0 or MathU Pro 1.1.
-
- See the file History.txt for more history information.
-
- System Requirements
- -------------------
- MathU Pro requires Palm OS 2.0 or higher, and 114K of RAM (164K including MathLib).
-
- Buying MathU Pro
- -----------------
- MathU Pro is just $34.95 and is available at PalmGear H.Q.(http://www.palmgear.com),
- Phone:817-461-3480, Fax: 817-461-3482).
-
- Installation
- ------------
- To install MathU Pro, simply unzip the archive you downloaded and use the
- install tool (or equivalent) to install MathUPro.prc, MathUEdit.prc, and
- MathLib.prc on your Palm device. You might also consider assigning the
- calculator button to bring up MathU Pro instead of the default calculator
- after syncing.
-
- Install the bundled function sets mthUUnits.pdb and mthUMathU+.pdb in the same way.
-
- MathU Pro requires MathLib.prc to be installed on the Palm Pilot. If you already
- have MathLib installed on your Palm device from some other program you don't need to
- install it again. MathLib is not part of MathU Pro. MathLib is a free shared library
- that can be used by any Palm OS 2.0+ program that needs IEEE 754 double precision
- math functions. It's distributed under the terms of the GNU General Public License,
- and is freely available with full source code and documentation at the MathLib
- Information web page (http://www.probe.net/~rhuebner/mathlib.html). It is not a part
- of MathU Pro, and you're not paying anything for its use; a copy is simply included
- in the archive for your convenience.
