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

// returns true
bool = isEven( new Number( 4 ) );
// returns true
bool = isEven( 5.0 );
// returns false
