function minmaxf( x, y ) {
	var out = new Float32Array( 2 );
	addon( x, y, out );
	return out;
}
Returns the minimum and maximum of two single-precision floating-point numbers.

@private
@param {number} x - first number
@param {number} y - second number
@returns {Float32Array} minimum and maximum values

@example
var v = minmaxf( 3.14, 4.2 );
// returns <Float32Array>[ ~3.14, ~4.2 ]

@example
var v = minmaxf( 3.14, NaN );
// returns <Float32Array>[ NaN, NaN ]

@example
var v = minmaxf( +0.0, -0.0 );
// returns <Float32Array>[ -0.0, 0.0 ]
