 | | Leading is commonly confused with ''line height'', which refers to the full height of a line of type (the size of the tallest letter in a font of type, plus the thickness of the leading). |
 | | Leading zeros are also generated by many older computer programs when creating values to assign to new records, accounts and other files, and as such are likely to be used by utility billing systems, human resources information systems and government databases. |
 | | Notable problems involving leading zeros include odometer rollover, calendar date formatting issues, apparently illogical alphabetization of filenames in which 1 is followed by 10, 11, 12, 2 followed by 21 22, 23, etc., and various instances of ambiguity between computer systems that generate and require leading zeros and ones that do not. |
