Explanation:
1. The square root of the floating-point number in the register specified by S is calculated, and
the result is stored in the register specified by D.
2. If the operation result stored in D is 0, SM600 is ON.
Example 1:
When X0.0 is ON, the square root of the floating-point number in (D1, D0) is calculated, and the
result is stored in (D11, D10).
Additional remark:
1. The value in the device specified by S only can be a positive value. If the value in the device
specified by S is a negative value, the operation error occurs, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#2003.
