We hope that by now you are familiar with number conventions in formal writing.
You can refer to Part 1 and Part 2 in this series, for a quick recap.
But it may not necessarily be appropriate for the document you're writing.
In English non-technical contexts, the style is often to write out numbers from one to nine as words, and then from 10 onwards as numbers (this is style used by the Associated Press and in some cases the Chicago Manual of Style).
Should be expressed as numerals I write numbers as words when they are used descriptively as part of the narrative, and with digits when they related to technical constants. First, the coefficient of 1 for reward is the best one to use.
Second, the algorithm takes 34 iterations to converge. I don't think it is an unnecessary complication, as long as you remember to be consistent.The APA version 6 style manual has an entire section starting from 4.31 on how to present numbers in text.The manual does include a general rule that numbers 10 and above should be expressed as numerals, but there are a wide range of exceptions.The modern scientific number style treats numbers more consistently by extending the use of “numerals” to most 1-digit whole numbers (1 to 9) that were previously expressed as words (one to nine).This style allows all quantities to be expressed in a similar manner.For example, if I need to write the number 6, I write 'six'.Recently though, I've been thinking this strategy adds unnecessary complications.when these numbers occur alone or as part of a larger number.When numbers greater than 100 are spelled out, do not use commas or “and” (e.g., one hundred forty-four).For these numbers, applying consistent logic (numerals for quantities and words otherwise) may make decisions about correct usage more difficult as they are also used in ways that are more like figures of speech than precise quantifications (“in one of the subjects…,” “zero-point energies”).Express the whole numbers zero and one as numerals only when: When a number is used idiomatically or within a figure of speech, spell out the word; however, like jargon, figures of speech may be inappropriate for scientifically oriented writing because they may not be readily understood by readers whose first language is not English.
