SCX is a Général-purpose high-precision calculator that combines standard mathematical functions with pricing functions needed in the Affaires/retail world. It's designed for simplicity and ease of use. SCX has a large, easy to read 15-digit display with 30 digits of internal precision. The Cost/Sell/Margin buttons provide a simple way to determine pricing information. Automatically uses ',' instead of '.' according to the Système preferences. Can be configured (via the Preferences app) as a drop-in replacement for the built-in Palm calculator. Compatible with all Palm devices. The registered version supports cut and paste of numbers between applications (via the menu, or the standard Command-C and Command-P Graffiti strokes), and retains the last calculation and memory values when you switch apps.
