Function Explanation

FRACTION is used to get the fraction part of a real number and the result is output to Out . The sign
of the result value should be the same as that of the input value.

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.
