Michael Brauer commented on OFFICE-2399:
----------------------------------------

I agree that we should just require that PI() shall be best approximation of pi that is possible. I don't think we need to say anything about rounding an truncation, since this is not specific to pi. Suggestion: Just say under semantics:

Semantics: This function takes no arguments and returns the (approximate) value of pi. Evaluators should use the closest possible numerical representation that is possible in their representation of numbers.

> What reads like requirements for Evaluators on PI sounds vague to me:
> "Evaluators are not required to represent pi exactly , but they should make an attempt to give an accurate result given their numerical representation method. Evaluators which use a fixed-length numerical representation should use the closest possible numerical representation."
> I don't think either of these represent meaningful statements. Suggest delete.
