function add( x, y ) {
	return ( ( x>>>0 ) + ( y>>>0 ) )>>>0; // asm type annotation
}
Computes the sum of two unsigned 32-bit integers `x` and `y`.

## Method

-   `>>> 0`: cast each operand to an unsigned 32-bit integer.
-   `+`: summation is exact as IEEE-754 integer addition of two unsigned 32-bit integers fits inside 53-bit range.
-   `>>> 0`: keep the low 32 bits.

@param {integer} x - first input value
@param {integer} y - second input value
@returns {integer} sum

@example
var v = add( 1>>>0, 5>>>0 );
// returns 6

@example
var v = add( 2>>>0, 5>>>0 );
// returns 7

@example
var v = add( 0>>>0, 5>>>0 );
// returns 5
