 Function Explanation

COS is used to calculate the cosine of the input parameter In 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.
