MATHLIB Function
Return X raised to the Y power.
POWER(X_FV, Y_FV)
X_FV
A non-zero floating point value that you want to use for the base.
Y_FV
A positive floating point value that you want to use for the exponent.
Description
Use this function to return X raised to the Y power. If Y is 0.0, the function returns 1.0. If X is negative and Y is not a whole number (that is, Y has a non-zero fractional part), the function computes the value using only the integral part of Y.
Errors
POWER: base = 0 and exponent < 0; returning 0.0.
X was specified as 0.0 and Y as negative, so the function returned the value 0.0 and placed this message in the ESL errorlog.
