function isNonPositiveFinite( value ) {
	return (
		isNumber( value ) && value.valueOf() <=0 && value.valueOf() !== NINF);
}
Tests if a value is a number object having a non positive finite value.

@param {*} value - value to test
@returns {boolean} boolean indicating if a value is non positive finite

@example
var bool = isNonPositiveFinite( -3.0 );
// returns false

@example
var bool = isNonPositiveFinite( new Number( -3.0 ) );
// returns true
