Coptic number font
Ⲃ ͵ ⲒⲆ

(2014 as a Coptic number) 
The formation of the Coptic numbers , like the letters of the Coptic alphabet itself, is derived from the Greek system . The letters of the alphabet are assigned numerical values according to their position. However, there are three special features:
 The six is represented with the letter Sou Ⲋ , which otherwise has no other function in Coptic, and in this function corresponds to the Greek stigma Ϛ .
 The Fai Ϥ stands for ninety , while in Greek the Qoppa Ϟ stands for this number.
 The 900 is represented by the letter Pˢis ^{ə} nše Ⳁ , whereas in Greek the Sampi Ϡ is used for this.
Especially in Bohairi , special italic variants of the Coptic letters were used to spell the numbers, some of which differed considerably in appearance from the normal letters.
education
As with the Roman numerals , the numbers are now formed additively, i.e. H. the characters for the ones, tens and hundreds are written next to each other in descending order, so you just have to add them up. To make the numbers stand out from the rest of the text, they are given an overline.
Big numbers
There are two options for displaying numbers greater than 999:
 With a trailing, commalike character (͵), the previous characters are multiplied by 1000, similar to the Greek system. Only numbers up to 999,999 can be represented in this way.
 The line over the thousand digits is doubled; tripled above the digits for millions etc.
Fractions
The stem fractions (½, ⅓, ¼ etc.) are written by putting an apostrophelike symbol ( ʹ ) behind the base of the fraction . An exception is the fraction ½, which is written with a special character ( ⳽ ).
Ordinal numbers
With Coptic ordinal numbers (1st, 2nd, 3rd, etc.) the number is simply prefixed with the word ⲙⲁ ϩ (mah, "fill").
Female numbers
If the number refers to a female word, a Ti ϯ without an overline is added to the number .
Examples
 ⲪⲞⲂ = 572
 ⲢⲔⲀ ͵ ⲨⲠⲌ or ⲢⲔⲀ ⲨⲠⲌ = 121,487
 Ⲋ ⳽Ⲇʹ = 6.75
 ⲙⲁ ϩ Ⲏ ϯ = the eight millionth
Numerical values of the letters
In the first column of letters the regular Coptic letter is given and in the second column the italic number variant. Since these were only included in the Unicode standard in 2014 ( Unicode block Coptic numerals ), hardly any font supports them.
