The flat height and baseline are centered on the round top and bottom of the zero and the difference or resulting overshoot value should be evenly distributed. Inferior numerals are commonly placed descending below the baseline in numerals used for scientific notation and on the baseline for numerals intended to be used as shilling fraction denominators. There are traditionally two alignments for inferior numerals. The most useful for text and scientific notation is an alignment that descends below the baseline approximately half the inferior numeral's height. The alignment commonly used for setting shilling fractions is on the baseline.
Many typefaces also have shilling fractions with denominators that descend.
The fraction bar will have a negative right and left sidebearing in most cases. The top and bottom of the bar are design dependant and commonly at the visual top and bottom of the figure height. The left sidebearing should be the same as other fractions with a numerator one. The right sidebearing should be adjusted to space well when an inferior baseline numeral follows. The numerator aligns with the figure height and at the same position as the one in other fractions.
