FC
FLOOR is used to get the integral part of a real number. The output value is the
integral part of the real number subtracted by 1 if the input real number is a
negative number.

 Function Explanation

FLOOR is used to get the integral part of a real number and the result is output to Out. The output
value is the integral part of the real number if the input real number is a positive number. For
example, the output value is 3 if the input value is 3.5. The output value is the integral part of the real
number subtracted by 1 if the input real number is a negative number. For example, the output value
is -4 if the input value is -3.5.

Users can choose different data types for the input parameter in this instruction. But the data type of
the output parameter is restricted to 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.
