The EXP math function calculates the exponential function (e raised to the power of a numericExpression).
Syntax
- result = EXP(numericExpression)
Description
- 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)
