[ 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.
