PGRM C

This emulator is just a toy. Use it 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 (+, -, * or x, / or :)
'x' is the same as '*' (multiplication)
'=' equivalent to '+' (same key in most keyboards)
Enter/Return or Space = ENTER
Modifiers: (F, G, S, R) map to (f, g, STO, RCL) modifiers
H = CHS (change signal)
P = EEX
A, B, C, D, E map to top-row keys: square, exponential, power of 10, power and reciprocal
! = also maps to power (y**x)
\ = also maps to reciprocal (1/x)
I, J, K map to trigonometric function keys (SIN, COS, TAN)
Y = swap x with y (x<->y)
N or down arrow = Rotate down stack (R-down)
W = Add statistical tuple (sigma-plus key)
O = On/Off key (toggles between decimal point and comma, and also saves memory as a cookie)
U = GSB key
T = GTO key
[ = R/S key
] = SST key
? = show memory dump (ugly HTML, mostly for debugging or plain curiosity)
Z = correct typing (Backspace also works in some browsers)

In case you need help to use the advanced features of 11C, take a look on this page, there is a quick reference guide in there.

If you prefer a simpler calculator (with the basic financial and arithmetic operations) or if you don't know the RPN notation, you can try this form-based calculator instead.
