Editing Digamma (section)

==Numeral==
Digamma/wau remained in use in the system of [[Greek numerals]] attributed to [[Miletus]], where it stood for the number 6, reflecting its original place in the sequence of the alphabet. It was one of three letters that were kept in this way in addition to the 24 letters of the classical alphabet, the other two being [[koppa (letter)|koppa]] (ϙ) for 90, and [[sampi]] (ϡ) for 900. During their history in handwriting in late antiquity and the Byzantine era, all three of these symbols underwent several changes in shape, with digamma ultimately taking the form of "ϛ".

It has remained in use as a numeral in Greek to the present day, in contexts comparable to those where Latin numerals would be used in English, for instance in [[regnal number]]s of monarchs or in enumerating chapters in a book, although in practice the letter sequence ΣΤ΄ is much more common.
