I wrote a simple extension to convert a number into a hours and minutes string in the ##:## format. This seems like a good way to do it, but let me know what you think.Number.prototype.display_hours_minutes = function () {  var remainder = this % 1;  var remainderTime = new Date(remainder * 3600 * 1000);  return ('0' + Math.floor(this)).slice(-2) + ':' + ( '0' + remainderTime.getMinutes()).slice(-2);};So this turns something like 53.34 into 53:20
