Numbers in Sentences¶
PerfectIt checks if numerals appear in sentences. It will suggest there may be a possible issue if numerals appear in some sentences while numbers are spelled out in other sentences. PerfectIt only raises an issue if the numbers are from a similar grouping. In other words, it will find an issue if the number ‘4’ and the word ‘seven’ are both used but it will not find an issue if the number ‘4’ and the word ‘twenty-seven’ are both used. The default categories for this split are:
Numbers from 1 to 10
Numbers from 11 to 20
Numbers from 21 to 99
Style guides often suggest that authors should spell numbers out rather than use numerals in sentences. However, they typically suggest that there are instances where numerals are preferred.
Such usage varies between guides but may include numerals for:
Numbers expressed in thousands, millions, billions, etc [e.g. 4 billion]
Ages [e.g. 12 years old]
Measurements [e.g. 23 miles]
Ranges [e.g. 4 to 7]
Categories/lists of groups [e.g. 7 of 10 dentists]
Ordinals [e.g. 4th, 6th]
PerfectIt has been designed to focus on instances where numerals in sentences are most likely to be issues. As a result, PerfectIt usually will not find an issue if the usage is in any of the above categories.
Customizing the Check ¶
You can set preferences for numbers in sentences in the Settings tab of the style sheet editor. You can set a preference for each range of numbers separately. In addition, you can switch the ranges to check to:
Numbers from 0 to 9
Numbers from 10 to 19
Numbers from 20 to 99
