Q: Question: I'm referring to the peculiar habit I sometimes see in formal documents, where a number is given numerically after it's spelled out. It seems quite redundant: I need five (5) kumquats, stat! (Though it isn't always in a legal context, might it be related to this answer on this question?) 
Answer: I looked into this myself recently and couldn't find a definitive answer. The best I came up with was that numeric values in a formal document or contract are often crucial to its purpose. Restating a number in parentheses after spelling it out is a way to ensure the reader that the number is correct. It also draws the eye to the numbers, allowing for quick perusal of a document, say a purchase order. These are practical reasons; whether there is some historic reason for it I do not know.

A: no
