Is there a difference between bracket and no bracket for below case? The return result is different. If i do a .toFixed(2) to the value, it causes 1 cents difference.

var x  = ( 103.5 * 15 / 100  );
var x1 = ( 103.5 * ( 15 / 100 ));

alert(x); //15.525 => after round to 2 decimal : 15.53
alert(x1); //15.524999999999999 => after round to 2 decimal : 15.52
