HP-12C Widget For Mac

HP-12C Widget calculator is only a toy. You may use it but it's at your own risk.

There are some key bindings that make the emulator easier to use in typical usage:

· Numbers, decimal point/comma and arithmetic (+,-,*,/). · Enter/Return = ENTER. · C = CLx (Clear x). · H = CHS (change signal). · E = EEX. · Modifiers: (F, G, S, R) map to (f, g, STO, RCL) modifiers. · Financial: (N, I, P, M, V) map to (n, i, PV, PMT and FV) operations. · Percentage: (#, $, %) map to (T%, delta% and %). · != power (y**x). · = inverse (1/x). · X = swap x with y (xy). · D = Rotate down stack (R-down). · W = Add statistical tuple (sigma-plus key). · O = On/Off key (toogles between decimal point and comma, and also saves memory as a cookie). · [ = R/S key. · ] = SST key. · ? = show memory dump (ugly HTML, mostly for debugging or plain curiosity). Backspace = correct typing (Firefox only).
