function fromWordf( word ) {
	return addon( word );
}
Creates a single-precision floating-point number from an unsigned integer corresponding to an IEEE 754 binary representation.

@private
@param {uinteger32} word - unsigned integer
@returns {number} single-precision floating-point number

@example
var word = 1068180177; // => 0 01111111 01010110010001011010001

var f32 = fromWordf( word ); // when printed, implicitly promoted to float64
// returns 1.3370000123977661
