3.2.50 EXT_ - EXPONENTIATION

EXT_ function blocks, in firmware 1.30 and higher, will provide
an output that equals the Y input raised to the power of X input.
All negative values of input Y will be treated as 0.0. When input
Y is 0.0 and X is negative, the output will be set to the maximum
number (i.e. 1.17...e38).
