The return type matches the input type. DIV accepts SINT, INT, DINT, LINT, USINT, UINT, UDINT, ULINT, REAL, LREAL. Both inputs must share the same type.

IN2

Description

Return value

ANY_NUM

IN1 divided by IN2. Same type as the inputs.

Description

Returns IN1 divided by IN2. DIV(a, b) is the functional form of the / operator: a / b. Both forms are equivalent.

For integer types, division truncates toward zero. Division by zero causes a runtime fault.

Example

result := DIV(42, 6);   (* result = 7 *)
result := 42 / 6;       (* result = 7, operator form *)
result := 7 / 2;        (* result = 3, truncates toward zero *)
