Arabic numerals are the ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The term often implies a decimal number written using these digits (in particular when contrasted with Roman numerals). However, the term can also refer to the digits themselves, such as in the statement "octal numbers are written using Arabic numerals." The term Arabic numerals may be intended to mean the numerals used in Arabic writing, such as the Eastern Arabic numerals. The Oxford English Dictionary uses lowercase Arabic numerals to refer to Western digits, and capitalized Arabic Numerals to refer to the Eastern digits.
