SECTION NINE: USE OF NUMBERS
______________________________________________________
Generally, spell out whole cardinal numbers one through ten and ordinals first through
tenth (exceptions: citation of editions and of appellate districts). For other numbers, use
numerals (exceptions: syllabus paragraph numbers and Amendments to the United States
Constitution). When numerals and spelled-out numbers would both be used for items in
the same category within the same paragraph or series of paragraphs, numerals may be
used for all.
Spell out all numbers that begin a sentence.
Use numerals with the word “percent” and with abbreviated units of measure.
Numerals may be used for items that are part of a numbered series that are referred to by
their numbers, e.g., assignment of error No. 1, state’s exhibit No. 5.
The words “thousand,” “hundred thousand,” “million,” and so on may be used to replace
a string of zeros.
When using numerals and letters to abbreviate ordinals, do not use superscript letters:
3d and 21st, not 3 d and 21 st .
