MUL¶

Returns the product of two or more inputs.

FUNCTION MUL : ANY_NUM
  VAR_INPUT
    IN1 : ANY_NUM;
    IN2 : ANY_NUM;
    (* ... additional inputs ... *)
  END_VAR
END_FUNCTION

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

Inputs

Name	Type	Description
`IN1`	`ANY_NUM`	The first multiplicand.
`IN2`	`ANY_NUM`	The second multiplicand.

Outputs

Name	Type	Description
Return value	`ANY_NUM`	The product of IN1 and IN2. Same type as the inputs.

Description¶

Returns IN1 multiplied by IN2. MUL(a, b) is the functional form of the * operator: a * b. Both forms are equivalent.

For integer types, overflow behavior wraps around (modular arithmetic).

Example¶

Try it

Source

result := MUL(6, 7);   (* result = 42 *)
result := 6 * 7;       (* result = 42, operator form *)
