Omicron
From Wikipedia, the free encyclopedia
(Redirected from Ο)
Omicron (uppercase Ο, lowercase ο, literally "small o": o mikron, micron meaning 'small' in contrast to omega) is the 15th letter of the Greek alphabet. In the system of Greek numerals it has a value of 70. It is rarely used in mathematics because it is indistinguishable from the Latin letter O and easily confused with the digit 0. This letter is equal to the Phoenician letter Ayin. The sound procuced by the modern Greek Omicron is most similar to the modern English sound "aw", as in 'law'.
In Unicode the capital letter is codepoint U+039F and the lowercase is U+03BF.
The upper-case letter of omicron (O) was originally used as a symbol for Big O notation, representing the asymptotic rate of growth of a function in mathematics.
