 Function Explanation
 RadToDeg is used to convert the input parameter In to degrees and the result is output to Out. That
is, Out =( In/π)* 180.
 The units of In and Out are radian and degree (°) respectively.
 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.
