Function Explanation

TRUNC is used to get the integral part of a real number 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 only LINT. An error will occur during the compiling of the software if the data
type of the output parameter is not LINT.

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.
