In Microsoft Excel, you can use either of two methods for using a custom number format to display leading zeros. Use one method for fixed-length numbers and use the other method for variable-length numbers. Method 1: Fixed-length Numbers When you want to display leading zeros for a fixed-length number, create a custom format with the same number of zeros 0 as digits that you want to display.

For example, if you want to display a fixed-length number with five digits, create a custom number format with five zeros. Example 1: Use the format to display a number with five digits. When you use this format, the numbers that you type and the numbers that Microsoft Excel displays are listed in the following table.

Typed number Displayed number Example 2: Use the format when you want the number to appear as five digits followed by a hyphen and four more digits.

Typed number Displayed number Method 2: Variable-length Numbers When you want to display leading zeros for variable-length numbers, create a custom format with the same number of zeros 0 in quotation marks as leading zeros that you want to display, followed by the number sign.

But to fit the string into a greater container prepending 0 we must write our own function. The one here proposed has no a flag for the alignment of the result inside the containing string.

This is actually the easiest kind of numeric output to achieve in COBOL, because it requires no adjustments from the way numbers are stored internally in fixed-point decimal. In this case, we have 9 a decimal digitrepeated five times; then Vthe decimal point cf.

Greater flexibility is available via the Formatting package, which provides an implementation of Python's format specification mini-language.

Custom function builds on the supplied 'print using ".

For example:. Will return "alohaaaaaa". Note the element type of a String is a Char, hence the single quotes around the 'a'. Your problem is a bit different since you need to prepend characters instead of appending them.

Well you could say this solution is better because at least the digits are still correctly aligned in that particular case, unlike the accepted solution.
