Technically, it doesn't matter that it's stored in binary. All that matters is that it's stored in some way that you can perform division on. I used to do this kind of thing in assembly language, pushing digits onto the stack, then popping them off afterward. (It's actually easier to make a column of numbers right-justified, as you can simply create a buffer of the right size - assuming you're working with a machine word and can know the maximum size - and populate it from the far end.) But yes, this is the standard way to do base conversions. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
