Purpose:
Calculator II is a pleasant looking color multi-function calculator that runs as an application under system 6.x or System 7. The calculator was written as an application to be run under MultiFinder or System 7 alongside other applications. It improves on Apple’s original calculator by adding trigonometric functions, functions for base 10 and natural logorithms and their inverses, hex-to-decimal and decimal-to-hex conversion, a percent increase/decrease key, a memory function for storing values across uses of the program, and all of these functions can be invoked by using the F-Keys on the Apple Extended keyboard (F5 - F15). The calculator also allows users to correct trailing digits of values entered on the display of the calculator through the use of a backspace key. A Ticker Tape is also provided to display the results of past calculations. Balloon help and general information about the program is available under either the Help menu under System 6.x or the Balloon Help menu under System 7. This software is being distributed as FREEware so give it a try and let me know what you think!
This version of the calculator contains several bug fixes and enhancements:
• Fixed a couple of Balloon Help bugs that caused balloons to appear or not appear at inappropriate times.
• Numbers copied to the clipboard from the calculator’s display no longer contain leading spaces.
• The calculator no longer permits the errant factorial calculations of negative numbers and 0.
• Fixed a bug using the HEX and DEC keys successively to convert numbers between hexadecimal and decimal.
• Changed the creator of the Calculator to ‘calc’ from ‘CALC’ to make accessing its bundle more realiable.
• The Calculator now saves its preferences in a Prefs File rather than inside itself. This will permit future updates of the program with Updaters like UpdateMaker.
• A new Info item was added to the Help Menu to thank all the people that have helped to make Calculator II a success.
This application has been explicitly tested under Systems 6.0.7, 7.0 (with and without System 7 Tuneup 1.1.1), and 7.1 with the Hardware Enablers. Testing was performed using a IIcx, Classic, Quadra 700, and PowerBooks 165c, 170 and Duo 230. Previous versions have run successfully on LCs and SE/30s.
2. Base 10 and Natural logarithms and their inverse functions.
3. Square and Square root functions.
4. Conversion from HEX numbers to decimals and vice versa. NOTE: HEX values must be entered in uppercase only and cannot exceed the value 0xFFFFFFFF.
5. Power and nth root functions.
6. Ability to correct trailing digits of values being entered on the calculator’s display.
7. Support for complete operation of calculator functions via the Apple Extended Keyboard (F5 - F15 required).
8. Ability to cut, copy and paste to and from the clipboard.
9. Balloon help is available for menus, About Dialog box, calculator keys, and the icon in the Finder.
10. General information about the program (Calculator II ReadMe document) is also available under the Help menu under Systems 6.0.x or 7.
11. Calculator remembers last used position on screen.
12. Shift key can be used with function and Clear keys to execute 2nd functions (e.g. arcsin instead of sin). When used with the Clear key only the last entry is cleared and not the entire equation. Likewise, the shift key can also be used with the mouse to access the 2nd Functions.
13. Calculator II retains the contents of its memory across uses of the program.
14. Calculator is AppleEvent aware of the core suite of events.
15. Through the use of the percent key, it is now possible to calculate percent increase or decrease. For example, it is now possible to enter 5 - 3.2% = 4.84! The percent key can also be used with a number to divide by 100 as in 5% = .05.
16. Ticker tape can be displayed by selecting Show Ticker Tape under the Edit menu to capture a history of performed calculations. Contents of tape may also be copied to the clipboard for use in another application.
Keyboard Map for Function Keys:
The function keys that appear on the calculator are mapped to the Function keys F5 - F15 on the Apple Extended Keyboard. Here is the correspondence map:
F5=sin
F6=cosine
F7=tangent
F8=2nd Function
F9=Value of PI
F10=Natural Log
F11=Base 10 Log
F12=Backspace Key
F13=Power function
F14=Square root function
F15=Square function
Shift + F5=arc sin
Shift + F6=arc cosine
Shift + F7=arc tangent
Shift + F9=Factorial function
Shift + F10=Constant e raised to a power.
Shift + F11=Constant 10 reaised to a power.
Shift + F13=Nth Root function
Shift + F14=Cubed Root function
Shift + F15=expression 1 divided by x
Other keys mapped to functions on the calculator:
c, Clear=Clear function
ESC = (Same as Clear/No Function)***
*, x=Multiplication
X=Memory Enter
R=Memory Recall
M=Memory Add
?=About Dialog box
Delete=Backspace function
Enter=Equal function
` or . = Reverse sign of number on display***
% = Percent increase or decrease.
Shift + Clear or Esc = Clear Last Entry, not just last digit.
Clear + X = Clear Memory.
2nd Decimal point in any number = reverse sign of number ***
***Depends upon settings in Preferences Dialog Box.
Future Plans for Calculator II:
1. Force Calculator to solve equations using the standard Hierarchy of Operators.
2. Option to display commas every 3 digits in results window.
3. Switch to display Statistical, Business, Scientific, or Programmer functions.
4. Option to display negative numbers in red color or parentheses instead of with leading negative sign.
5. Allow for the print and save (TEXT) of the ticker tape.
