What's the best way to get the most accurate value for pi in a VBA
function?

Excel 2007 has a pi() worksheet function, but there doesn't appear to
be a corresponding VBA function. The best I could come up with is

C = 2 * Application.WorksheetFunction.Pi() * R

That works, but it's a litte messy.

This helped. Thank you.

By definition, pi = 4*arctan(1).
?4*atn(1)
3.14159265358979

Since the value of pi won't ever change (barring a fundamental change in the
universe) I just assign it to a constant if I need it:

Const PI = 3.14159265358979


I failed to notice that this thread dates from April 28, 2009.
did not give a reason for resurrecting it.

I like Const PI = 3.14159265358979
I prefer Const PI As Double = 3.14159265358979
but there is no difference in meaning. YMMV. ;)
