This is what allows pifs to work!
I'm a layman here and not a mathematician but how does it store the complete value of pi and not rounded up to a certain amount? Or do one of the libraries generate that?
You generate it when needed, using one of the known sequences that converges to ฯ. As a simple example, the
pi()recipe here shows how to compute ฯ to arbitrary precision. For an application like pifs you can do even better and use the BBP formula which lets you directly calculate a specific hexadecimal digit of ฯ.
