This function returns the value of the mathematical base e to the power of the given parameter (in other words, this is equivalent to the mathematical expression evar). This is the opposite to the function LN, ie. var=LN(EXP(var)).
QDOS supports var in the range -512…511. The approximate value of e can be found by:
returns the value 1 - as any good mathematician knows, anything to the power of 0 returns the value 1.
LN returns the natural logarithm of the given value.
