Why RedCrab?
No one today would want to work with word processing program that simulates a typewriter, for example, no copy, paste and edit. For typo errors, whole text must be rewritten. But most PC calculators are just unflexible simulations of pocket calculators.

RedCrab is a calculator that exploits the possibilities of PC's. Easy to use like a pocket calculator, but provided with full screen editor, which supported corrections, saveing and printing as a word processing program.

Several tasks can be written in the same worksheet. Results can be adopted in other mathematical problems as in a spreadsheet program. Images and texts can imported to describe complex calculations.

Whats New:
Update Version 5.1.1 (Security Update)
Edit Box improved. Text formatting problems fixed. Word Wrap function implemented.
Display of chart boxes and chart series improved.
Result formatting problems of Greek letters fixed.
RedCrab Calculator V is more than an update.
Version V is converted completly to a new developer system. The new system is a prerequisite for current and future developments.
Visible feature is the new WPF interface. For example, all buttons have tooltips, which are partially supplemented with graphic or examples.
This inevitably brought changes. Users of older versions of RedCrab please read the ReadMe file in the upgrade
