function ssorthp( N, order, x, stride ) {
	addon( N, order, x, stride );
	return x;
}
Sorts a single-precision floating-point strided array using heapsort.

@param {PositiveInteger} N - number of indexed elements
@param {number} order - sort order
@param {Float32Array} x - input array
@param {integer} stride - index increment
@returns {Float32Array} input array

@example
var Float32Array = require( '@stdlib/array/float32' );

var x = new Float32Array( [ 1.0, -2.0, 3.0, -4.0 ] );

ssorthp( x.length, 1.0, x, 1 );
// x => <Float32Array>[ -4.0, -2.0, 1.0, 3.0 ]
