isEven

Test if a value is an even number.

Usage

var isEven = require( '@stdlib/assert/is-even' );

isEven( value )

Tests if a value is an even number.

var Number = require( '@stdlib/number/ctor' ); var bool = isEven( 6.0 ); // returns true bool = isEven( new Number( 6.0 ) ); // returns true bool = isEven( 3.0 ); // returns false bool = isEven( -3.14 ); // returns false bool = isEven( null ); // returns false bool = isEven( NaN ); // returns false

isEven.isPrimitive( value )

Tests if a value is a primitive even number.

var Number = require( '@stdlib/number/ctor' ); var bool = isEven.isPrimitive( -4.0 ); // returns true bool = isEven.isPrimitive( new Number( -4.0 ) ); // returns false

isEven.isObject( value )

Tests if a value is a Number object having an even number value.

var Number = require( '@stdlib/number/ctor' ); var bool = isEven.isObject( 4.0 ); // returns false bool = isEven.isObject( new Number( 4.0 ) ); // returns true

Examples

var Number = require( '@stdlib/number/ctor' ); var isEven = require( '@stdlib/assert/is-even' ); var bool = isEven( 4.0 ); // returns true bool = isEven( 0.0 ); // returns true bool = isEven( new Number( 4 ) ); // returns true bool = isEven( 5.0 ); // returns false bool = isEven( NaN ); // returns false bool = isEven( '5' ); // returns false bool = isEven( null ); // returns false
