Revision as of 21:48, 22 February 2023

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 or DOUBLE variable or as literal number, then it must be less than or equal to 88.02969 or an "overflow" error will occur.
When passing numericExpression as a _FLOAT variable, then it must be less than or equal to 709.782712893 or an "overflow" error will occur.
- You may also pass literal numbers as _FLOAT by adding the ## type suffix to it, 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)
