[ yet another pi calculation program in bf
Just like for pi16.b the accuracy of the result depends on the cellsize:
- using 8 bit cells causes an overflow after 4 digits
- using 16 bit cells causes an overflow after 537 digits
- using 32 bit cells causes an overflow after several millions of digits
It's about ~38 times shorter than pi16.b, ~364 times faster and works with
not-wrapping (bignum) implementations.
