function toWords( out, x ) {
	addon( out, x );
	return out;
}
Splits a double-precision floating-point number into a higher order word (unsigned 32-bit integer) and a lower order word (unsigned 32-bit integer).

@private
@param {Uint32Array} out - output array
@param {number} x - input value
@returns {Uint32Array} output array

@example
var Uint32Array = require( '@stdlib/array/uint32' );

var out = new Uint32Array( 2 );

var w = toWords( out, 3.14e201 );
// returns <Uint32Array>[ 1774486211, 2479577218 ]

var bool = ( w === out );
// returns true
