Arabic numeral variations

There are various stylistic and typographic variations to the Arabic numeral system. == Old-style numerals == The numerals used by Western countries have two forms: lining ("in-line" or "full-height") figures as seen on a typewriter and taught in North America, and old-style figures, in which numerals 0, 1 and 2 are at x-height; numerals 6 and 8 have bowls within x-height, and ascenders; numerals 3, 5, 7 and 9 have descenders from x-height; and the numeral 4 rests along the baseline.
