snapCalc for OS5 5.6.3
(Edit)SnapCalc allows you to pop up a basic calculator from within any PalmOS application, do some calculations, and, if you choose, copy the result to the underlying application. SnapCalc also allows you to paste a value to the display and use it in your calculations. SnapCalc5 is a standalone program. It does not require MATHLIB.PRC but it doesn't do trig functions either.
