- 4Calc v1.1
- by
- Paul D. Cardwell
- 1993, 94
-
- Purpose : To make calculations a breeze (ala four banger).
- Syntax : 4Calc (cli example: 1> 4Calc) or Click on it from Workbench.
- OS Type : AmigaOS 2.04 and greater should work.
- CPU used: Amiga 4000 (OS 3.0)
- Compiler: DICE C v2.07.54R
-
- You can add this little goodie to ToolManager,ToolsPref,WMS 3.00, or any
- program lauching utility.
-
- Installation:
-
- Cli: Copy the files from the archive to any where you want them.
- Workbench: Just drag and drop them into a drawer.
-
-
- Usage:
- You can use the keypad or associated keys to use the calculator.
-
- KEYPAD definitions:
- ------------------
- <ENTER>,= equal (calculate answer)
- <(>, CE Clear all, and start all over
- <)>, C Clear last number entered
- <*>, Multiply
- </>, Divide
- <+>, Add
- <->, Subtract
- <0..9,.> -- no explaination needed --
-
- If you do not have a keypad use the associated keys on the keyboard.
-
- You may also use the buttons (point-n-click) to do the same as
- the above keys do.
-
- Description (rough) on how it works:
-
- The rectangle box (string requester) is where you can click in
- and add or remove numbers and decimal point via keyboard. I thought
- this would be a little nifty feature. Of course whatever you enter
- it will strip out all non digits and no more than one decimal
- allowed.
-
- 4Calc allows you to do continous operator functions:
- Say you clicked in: 10 + 2 - 6 * 2 : followed by < enter > or
- by clicking < = > it would produce the desired result. Plus
- as each operator passes it completes that calculation.
-
-
- History:
- Why bother since OS 2.04+ comes free with a calulator?
-
- I wanted to learn more about Amiga programming.
-
- v1.0 -- Original mockup and not well written :) ...I was just
- playing around.
- v1.1 -- Second release with many bugs removed and better handling.
- I received numerous complaints.
-
- Added: Continous calculations (to end it press CE or ( ).
- Made an Icon for both 4Calc and this readme file.
- Made it so you can't have anything from hell in the
- string requester (after entry it strips it).
-
-
- Future:
- * Better documentation and expression evaluator (i.e. from string
- requester: 4*(5^2)+3-1 ).
- * Paper roll (be able to watch calculations as they are made/ran).
- * Maybe a ton of math functions beyond the four?
