Math.round does the job with a little more extra work. Divide by 5, round it, multiply it back by 5. It is a method I used quite a bit in the past. Here is a simple snippet to show it is working.

function RoundTo(number, roundto){
  return roundto * Math.round(number/roundto);
}

alert(RoundTo(543.55, 5));
alert(RoundTo(541.99, 5));
