9. Converting String to Integer without losing leading zero's

Your question here about passing "bits" doesn't seem to have anything to do with the original question about preserving leading zeroes in integers. If you're having a problem with the number of bits you're passing, then you must not be passing an integer. Would you like to display the code you're using to pass those bits?

10. Counting digits in an integer value, including zero

Hello, I'm curious if this is possible at all. Imagine if a user enters the number 00005 from his keyboard, and we were to count all the digits, including zeros, in this number, how would we go about doing it? I see that any value entered from the keyboard that includes a zero in the beginning automatically cuts off. How can ...
