See this discussion.

Ah, yes. Thank you!

That link led me even further back, to this discussion, where Hugh Steers points out that you need lots of digits of pi if you want to calculate the sine, in radians, for very large arguments. He explained this to me once when we were discussing his BCD20 floating-point library, which I had noticed contained pi to several hundred digits.
