Leading zeros are zeros that appear at the beginning of a number, before any non-zero digit, they are not significant.

To add leading zeros à des nombres, enter the numbers in the textarea and either the quantity of `0`s to add or the desired length of digits for the number and dCode will calculate the required number of zeros. This operation is sometimes called `zfill`.

__Example:__ `123` formatted for a length of `8` gives `00000123`

__Example:__ `123` formatted with `5` initial zeros also gives `00000123`

To deformat a number and remove zeroes at the start, enter the numbers the field and all leading zeros will be removed.

__Example:__ `000123` will be converted to `123`

__Example:__ `0.123` stays unchanged as `0.123`

To convert `00000123` to `000123` then, first remove the `0`s and then pad left 3 zeros.

Leading zeros are often used to ensure that a number has a certain number of digits and to maintain consistent formatting.
