The EXP math function calculates the exponential function (e raised to the power of a numericExpression).

result = EXP(numericExpression)

e is defined as the base of natural logarithms or as the limit of (1 + 1 / n) ^ n, as n goes to infinity.
When passing numericExpression as a SINGLE variable or as literal number without an explicit type suffix, then it must be less than or equal to 88.02969 or an "overflow" error will occur.
When passing numericExpression as a DOUBLE or _FLOAT variable, then it must be less than or equal to 709.782712893 or an "overflow" error will occur. You may pass literal numbers as DOUBLE or _FLOAT values by explicitly adding the # or ## type suffix to it respectively, e.g. result = EXP(678.9##).
The value returned is e to the exponent parameter (e = 2.718282 approximately).
The precision of the returned values depends on the provided result variable type, but is usually not higher than that of the given numericExpression.
Positive exponent values indicate the number of times to multiply e by itself.
Negative exponent values indicate the number of times to divide by e. Example: e ^ -3 = 1 / e ^ 3 = 1 / (e * e * e)
