Any lib written in C or with C bindings would work in Objective-C.
You may find using binary coded decimal is a useful.
If you google for binary coded decimal library for osx
you get a number of libraries. I thought this one was interesting.

NSDecimal may help, but it's also of finite size, so it won't help
trying to print out the digits of pi to arbitrary precision, since
pi is infinitely long. Algorithms to print the digits of pi usually
emit the digits one at a time, so they are n

Hi,
I am writing an implementation of the Brent-Salamin algorithm for
calculating pi. I want to be able to display potentially a large
number of decimal places in the result (hundreds at least). However I
am finding that even using long double values in my calculation gives
me only the fi
