| * = SQRT(RDX) | square root. |
| * = LOG(RDX) | natural logarithm, i.e. log to base e (where e = 2.718281828...). |
| * = EXP(RDX) | returns the exponential, i.e. e to the power of the argument. This is the inverse of the natural logarithm. |
| * = LOG10(RD) | logarithm to base 10. |
Note that LOG10, which may be useful to compute decibel ratios etc., is the only one of this group which cannot be used on a complex argument.
