I want to convert all numbers to the nearest .25

So...

5 becomes 5.00
2.25 becomes 2.25
4 becomes 4.00
3.5 becomes 3.50

Thanks

Here is @Gumbo's answer in a form of a function:

var roundNearQtr = function(number) {
  return (Math.round(number * 4) / 4).toFixed(2);
};

You can now make calls:

roundNearQtr(5.12345); // 5.00
roundNearQtr(3.23); // 3.25
roundNearQtr(3.13); // 3.25
roundNearQtr(3.1247); // 3.00
