how can I zerofill a number without loosing decimals? I tried using sprintf but it deleted all my decimals, what I don't want.
I have the number 12.2 and I want it to look like 012.2, but sprintf gives me 012 and removes the decimals. The function I'm using is: sprintf('%02u', $number);
You have a good explanation of the sprintf format in the PHP manual, which applies to printf as well.
printf('%05.1f', 12.2);
Output:
012.2
