 Function Explanation
 The instruction is used to find the remainder of the division of two floating- point variables or
constants and the result is output to Out.
 The input variable and input variable or the input variable and output variable are allowed to be of
different data types in this instruction.
 Precautions for Correct Use
 The input variables are not allowed to omit. An error will occur during the compiling of the software
if any input variable is omitted. But the output variable is allowed to omit.
 The input value of In2 can not be 0. In other words, the divisor in the division operation can not be
0. The value of Out will be 0 if the value of In2 is 0.
