leading zeros
Left-side digit fillers
Leading zeros are zeros that appear before the first nonzero digit in a number: 007, 0042.
They don't change a number's value but serve formatting purposes—maintaining fixed-width fields, preserving significant digits, or meeting identifier conventions.
Spreadsheets and databases notoriously strip leading zeros from phone numbers and zip codes, treating them as numbers rather than strings of characters.
