This emulator is supplied as is. Use it at your own risk! Always double-check important calculations by other means.

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

- Numbers (including hexadecimal digits), 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: (M, G, S, R) map to (f, g, STO, RCL) modifiers.
**Note that this is a bit different from other HP-1xC emulators. The letter F goes to digit F (hexadecimal). The modifier "f" is tied to letter M ("modifier"). We felt that, in a calculator tailored especially for programmers and computer scientists, the F digit has more priority than the modifier.**- H = CHS (change signal)
- I, J, K, L map to numeric system keys (HEX, DEC, OCT, BIN)
- Y = swap x with y (x<->y)
- N or down arrow = Rotate down stack (R-down)
- O = On/Off key (toggles between decimal point and comma, as well as "apocryphal" display of word size and whole integer value)
- U = GSB key
- T = GTO key
- [ = R/S key
- ] = SST key
- ? = show memory dump (ugly HTML, mostly for debugging or plain curiosity)
- Z = BSP = correct typing (Backspace also works in some browsers)

In case you need help to use the advanced features of 16C, take a look on this online manual.

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.

Also, try our version for Android.
