Don't bother taking the zeros out. I would only output the % after each line is loaded not each number. Having said that to be honest even a huge map should loads so fast you won't need a loading bar for them. My games have a loading bar but it progress at key stages e.g. graphics are all loaded, sounds are all loaded, levels are all loaded, arrays are created etc so it only goes up in say 20% chunks. It still loads in about 1 sec flat on my PC.
