# % (modulo)

#### Availability

Flash Player 4. In Flash 4 files, the `%` operator is expanded in the SWF file as`x - int(x/y) * y`, and may not be as fast or as accurate in later versions of the Flash Player.

#### Usage

    expression1 % expression2

#### Parameters

None.

#### Returns

Nothing.

#### Description

Operator (arithmetic); calculates the remainder of `expression1` divided by `expression2`. If either of the `expression` parameters are non-numeric, the modulo operator attempts to convert them to numbers. The `expression` can be a number or string that converts to a numeric value.

#### Example

The following is a numeric example that uses the modulo (`%)` operator.

    trace (12 % 5);
    // returns 2
    trace (4.3 % 2.1);
    // returns approximately 0.1
