Built-In Functions
All computations are performed on numbers on the stack. If you perform a computation and the numeric entry contains an un-entered number f(x) automatically enters that number onto the stack and uses it as the first argument for the computation selected.
All computations require either one or two arguments. If a selected computation requires two arguments and the stack contains only one number no operation is performed and the stack is left untouched. Some computation buttons are marked with X and Y arguments. In all cases X is the last entry on the stack and Y is the second to last entry on the stack.
A list of all the computations keys and their arguments as well as computation keys with the alt key pressed and their arguments:
| button | expression | alt/button | expression |
| + | X + Y | none | |
| - | X - Y | none | |
| x | X * Y | none | |
| / | X / Y | none | |
| sin (x) | sin(X) | asin (x) | arcsin(X) |
| cos (x) | cos(X) | acos (x) | arccos(X) |
| tan (x) | tan(x) | atan (x) | arctan(X) |
| log (x) | log10(X) | 10x | 10 to power X |
| Ln (x) | loge(X) | ex | e to power X |
| 1/X | 1/(X) | x! | factorial of X |
| X2 | X squared | same | |
| sqrt X | square root (X) | Xth root Y | Xth root of Y |
| Yx | Y raised to the X power |

| mod(x) | returns the integer remainder of Y/X | same | |
| ip(x) | integer portion x | same | |
| fp(x) | fractional portion of x |
