Explanation
1. This instruction raises the single-precision floating-point number in S
the single-precision floating-point operation result in D.
2. D=POW[S +1，S ]^[S
1 1
3. For PLC with firmware V1.10.00 or previous versions, the value in S
in S can be either a positive or a negative number.

4. For PLC with firmware V1.10.10 or later versions, if the value in S
either a positive or a negative number. If the value in S
number either positive or negative.
5. Suppose the values in S
6. If the absolute value of the operation result is larger than the value that can be represented by floating-point
numbers, the value in D is 16#7F7FFFFF, and SM602 is ON.
7. If the absolute value of the operation result is less than the value that can be represented by floating-point
numbers, the value in D is 16#FF800000, and SM601 is ON.
8.
If the operation result stored in D is 0, SM600 is ON.
