Rule B.9: Numbers in Textual Sentences
B.10(a): Generally
TLR follows Bluebook Rule 6.2 and CMOS 9.2 for guidance on numbers in textual sentences. “One hundred” should be spelled out per CMOS 9.2 unless it is being used as a percentage, then the numeral 100 should be used.
Examples:
- Andrew is sixty-two years old. Cassidy is 102 years old.
- They burned, respectively, 117, 3, and 15 homes.
- Forty Staff Editors completed cite checks.
- There were one hundred marbles in the jar. The sign said 100% of the marbles were blue.
B.10(b): Four-Digit Non-Year Numbers
However, TLR does not follow Bluebook Rule 6.2(a)(vii) where a four-digit number is used, but is not in reference to a year. In such situations, a comma should be used to separate the last three digits.
Examples:
- The Act will expire in 2012.
- The referendum needed 9,352 votes to become law.
B.10(c): Generic and Approximate Quantities
Generic and approximate quantities are to be written out rather than in numerals, while exact quantities should typically be in numerals.
Examples:
- Over two thousand fans attended the Temple football game.
- The attendance at the Temple football game was 2,244, calling into question the need for a new stadium.
