rangeToPercent and percentToRange

Two very useful functions / formulas to convert a percentage number to any range values or any number to a percent range.

function rangeToPercent(number, min, max){
   return ((number - min) / (max - min));
}
 
function percentToRange(percent, min, max){
   return ((max - min) * percent + min);
}

Enjoy!
