The EXP() function returns the exponential (the natural anti-log) of a value.
The EXP() function returns the exponential of expr, that is, the mathematical constant e raised to the power expr. The value of e is about 2.71828.
If expr is a numeric array (a dynamic array where all elements are numeric), the EXP() function operates on each element in turn and returns a numeric array with the same structure as expr.
N = EXP(X)
This statement finds the natural anti-log of X and assigns this to N.
