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 natrual logorithms and their inverses, hex-to-decimal and decimal-to-hex conversion, 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. 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 fixed a bug which corrupted entered numbers after using any one of the memory keys. A help button was also added to the About Dialog to make users aware of the help facility.
This application has been explicitly tested under Systems 6.0.7 and 7.0 (with and without System 7 Tuneup 1.1.1). Testing was performed using a IIcx,Classic, and PowerBook 170. Previous versions have run successfully on LCs and SE/30s.
