Forms of decimal digits used in most parts of the Arabic world (for instance, U+0660, U+0661, U+0662, U+0663). Although European digits (1, 2, 3,…) derive historically from these forms, they are visually distinct and are coded separately. (Arabic-Indic digits are sometimes called Indic numerals; however, this nomenclature leads to confusion with the digits currently used with the scripts of India.) Variant forms of Arabic-Indic digits used chiefly in Iran and Pakistan are referred to as Eastern Arabic-Indic digits.
