| Command | Input | Output | Description |
|---|---|---|---|
| f.asin | Xreg | Xreg |
Calculate arcsine of Xreg Valid input range -1 <= Xreg <= 1 Calculation time increases as Xreg approaches |1| * Input range not checked * |
| f.cos | Xreg | Xreg |
Calculate cosine of Xreg Valid input range -2π <= Xreg <= 2π * Input range not checked * |
| f.exp | Xreg | Xreg |
Calculate exponential of Xreg This is e to the power of Xreg |
| f.ipwr <a> | Xreg |
Raise the Xreg to the power of <a> Integer input on command line Example: ipwr 3 Value of <a> must be an positive integer. |

| f.ln f.ln.rg f.ln.is |
Xreg | Xreg |
Calculate Natural Logarithm of Xreg Valid range Xreg > 0 Method: f.ln (default method = f.ln.is) f.ln.rg Iterative guess method f.ln.is Infinite Series |
| f.nroot <a> | Xreg | Xreg |
Calculate <a> root of Xreg <a> supplied on command line. Example, square root: f.nroot 2 Input must be positive integer >= 2 * Input range not checked * |
| f.sin | Xreg | Xreg |
Calculate sine of Xreg Valid input range -2π <= Xreg <= 2π * Input range not checked * |
Angular units are in radians.
Sin(x) was written to check calculation of pi
Arcsin(x) was written to check sin(x)
Ln(x) was written to check calculation of e
As you can see, this is not a full function calculator.
These limited functions were written to check results.
These functions have not been formally tested.
I don't recommend using these for general use.
