# isEven > Test if a 32-bit integer is even.
## Usage ```javascript var isEven = require( '@stdlib/math/base/assert/int32-is-even' ); ``` #### isEven( x ) Tests if 32-bit integer is even. ```javascript var bool = isEven( 5 ); // returns false bool = isEven( -2 ); // returns true bool = isEven( 0 ); // returns true ```
## Examples ```javascript var randu = require( '@stdlib/random/base/randu' ); var round = require( '@stdlib/math/base/special/round' ); var isEven = require( '@stdlib/math/base/assert/int32-is-even' ); var bool; var x; var i; for ( i = 0; i < 100; i++ ) { x = round( randu()*100.0 ); bool = isEven( x ); console.log( '%d is %s', x, ( bool ) ? 'even' : 'not even' ); } ```
