Forums Scripts & Popups How to place a comma in a long string of numbers

$bytes cannot do it even for extremely small number,if you want to support decimals, only regex will do a great job. For integer only, then $bytes will do the trick... until you use a very large integer.
With large integer, by default $bytes will stop being 'accurate' at the 2^53 limit. You could enable bigfloat, but that will make it slower AND is that is still limited (a much much larger value than 2^53 but still limited) whereas doing the operation on the string, via regex for example, is extremely fast and should be the prefered method here.
