- Introduction
- ------------
-
- PocketCalc is a basic four-function calculator, such as you might buy to put
- in your pocket and carry about with you. The difference is that you'll have
- problems putting your computer in your pocket :-) It was written as a project
- for the degree course I am on, so I had to write it, and I figured I might as
- well release it, for what it's worth...
-
-
- Requirements
- ------------
-
- PocketCalc requires MUI V2.2 or better in order to run (it was either that or
- write a shell-based interface), so you'll need to download it from Aminet or
- somewhere. It also requires Kickstart V37 or better to run. Mouse is optional.
-
- MUI is of course © Copyright 1994 Stefan Stuntz, and is brilliant :-)
- See below for more information.
-
-
- Installation
- ------------
-
- Simply copy PocketCalc and its icon whereever you want them, and double-click
- the icon to start, or you can use the shell if you prefer.
-
-
- Usage
- -----
-
- Er, who hasn't used a pocket calculator before? All the buttons have keyboard
- shortcuts, as follows:
-
- All digits are exactly what you'd expect them to be. The numeric keypad keys
- may of course be used in preference to the main ones. The decimal point and
- operator keys are as in the interface, except for 'x' and '÷' which are
- controlled by '*' and '/' respectively. The other buttons are controlled as
- follows:
-
- '=' 'Return' or 'Enter'
- 'AC' 'a'
- 'C' 'c'
- 'MR' 'Shift-r'
- 'M+' 'm'
- 'M-' 'Shift-m'
- 'Sqrt' 'r'
- 'x²' 's'
- '±' 'n'
- 'Pi' 'p'
-
- Pressing 'C' will clear the display, but not the current calculation (if any),
- so if you make a mistake in entering a number, simply press 'C' and re-enter it.
- 'C' will not clear the memory.
-
- Pressing 'AC' will clear the current calculation and the memory as well.
-
- If an error message appears (in the event that you try to divide by zero or to
- take the root of zero), pressing 'C' or 'AC' will clear it.
-
-
- Distribution
- ------------
-
- PocketCalc is freely distributable, provided you don't modify it in any way,
- and that all files in the archive go with it. In fact, it's probably best if
- you simply pass on the archive intact. You may delete any files you want for
- your own purposes, but you mustn't distribute an incomplete archive.
-
-
- Warranty
- --------
-
- None. If it goes wrong, it's not my fault. I can probably be persuaded to
- fix it (money helps here :-) if there is a bug. My e-mail address is at the
- top of this document.

- History
- -------
-
- 26/01/95 Project started. Basic design arrived at, and coding begun.
- User interface designed and written, plus input handling for
- digits. Decimal point not yet working. Leading zero suppression
- in place, however.
-
- 27/01/95 Decimal point working. Initial operation code written. Rather
- buggy... Functions not implemented as yet. Error function
- written, doesn't appear to be getting called.
-
- 9/02/95 Maths operations almost fixed, one or two little bugs to work out.
- Mathematical accuracy is lousy right now. Seems to be using
- about 16 bits! I'm trying to use 96 bits...
-
- 10/02/95 Accuracy fixed. Using the wrong maths library :-( Still not got
- around to fixing the other bugs. Error function working now.
- Implemented the 'AC' and 'C' functions.
-
- 26/02/95 All bugs finally fixed; Memory function implemented. Swapped the
- '.' and '0' buttons around.
-
- 27/02/95 First release; uploaded to Aminet.
