<P> The slashed zero is a representation of the number ' 0 ' ( zero ) , with a slash through it . The slashed zero glyph is often used to distinguish the digit `` zero '' ( `` 0 '' ) from the Latin script letter `` O '' anywhere that the distinction needs emphasis , particularly in encoding systems , scientific and engineering applications , computer programming ( such as software development ) , and telecommunications . It thus helps to differentiate characters that would otherwise be homoglyphs . It was commonly used during the punched card era , when programs were typically written out by hand , to avoid ambiguity when the character was later typed on a card punch . </P>
