 Function Explanation
 EXPT is used to perform the exponentiation operation with In as the base number and Pwr as the
exponent. And the result is output to Out.
 Users can choose different data types for the input parameter in this instruction. But the data type
of the output parameter is restricted to LREAL. An error will occur during the compiling of the
software if the data type of the output parameter is not LREAL.
 Precautions for Correct Use
 The input variable is not allowed to omit. An error will occur during the compiling of the software if
the input variable is omitted. But the output variable is allowed to omit.
