Editing Arabic numerals (section)

==Encoding==
The ten Arabic numerals are encoded in virtually every character set designed for electric, radio, and digital communication, such as [[Morse code]]. They are encoded in [[ASCII]] (and therefore in [[Unicode]] encodings<ref>{{cite web |url=https://www.unicode.org/charts/PDF/U0000.pdf |title=The Unicode Standard, Version 13.0 |website=unicode.org |access-date=1 September 2021 |url-status=live|archive-url=https://web.archive.org/web/20010602232829/http://www.unicode.org:80/charts/PDF/U0000.pdf |archive-date=2 June 2001 }}</ref>) at positions 0x30 to 0x39. [[Mask (computing)|Masking]] all but the four least-significant binary digits gives the value of the decimal digit, a design decision facilitating the digitization of text onto early computers. [[EBCDIC]] used a different offset, but also possessed the aforementioned masking property.
