    // 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( 5.0 );
    // returns false
    
    bool = isEven( NaN );
