A font with a slashed zero has a distinctive design where the zero is replaced by a diagonal slash, making it easily distinguishable from an uppercase “0.”
This design element was originally used to distinguish the number zero from the letter O in typewritten documents. Today, fonts with slashed zeros can be found in both digital and print media and are often used in technical or mathematical contexts where clarity and precision are important.
