* Returns the minimum and maximum of two single-precision floating-point numbers and assigns results to a provided output array.

* @param {number} y - second number
* @param {Collection} out - output array
* @param {integer} stride - output array stride
* @param {NonNegativeInteger} offset - output array index offset
* @returns {Collection} minimum and maximum values

* @example

* @example
* var out = [ 0.0, 0.0 ];
* var v = minmaxf( 3.14, NaN, out, 1, 0 );
* // returns [ NaN, NaN ]
*
* @example
* var out = [ 0.0, 0.0 ];
* var v = minmaxf( +0.0, -0.0, out, 1, 0 );
