MOD

Modular arithmetic division, remainder stored in output variable

MOD divides the value of the first input variable by the value of the second. The remainder of the integral division (e.g. 5 : 2 = 2, remainder = 1) is written into the output variable.

Parameters

Input

Unnamed input (INT, DINT, UINT, UDINT): 1st input: dividend
Unnamed input (INT, DINT, UINT, UDINT): 2nd input: divisor

Output

Unnamed output (INT, DINT, UINT, UDINT): Output as input: remainder

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		dividend: INT:=11;
		divisor: INT:=4;
		remainder: INT:=0;
	END_VAR

LD body

This example uses variables. You may also use constants for the input variables. Dividend (11) is divided by divisor (4). The remainder (3) of the division is written in remainder.
