"integral" is an adjective and "integer" is a noun. "integer expression", though gramatically wrong (or, at best, an elision of two nouns), is perfectly clear and unambiguous, whereas "integral expression", though gramatically correct, hits some people as "built-in expression" and trips others up as an unfamiliar and rare word whose meaning is uncertain - for what gain? Personally, I like "integral expression", but then I'm a native-English speaker and UK academic with an extended vocabulary. For world-class dovumentation, it depends whether it's more important to be clear and unambiguous to all readers or an object lesson in type-correct advanced English. I'd say our friend has pointed out a tiny place where it could be made a little more effective in the first of these purposes. M
