The same as the last one for the number Pi, except that only the first X digits are allowed to be mapped into instructions and then executed. So, an infinite loop and a finite size algorithm obtained from the first few hundred (more or less) instructions. The decimal dot is merely a comment.
3.1415 … is perhaps INC A; A+=1/A; NOP; A+=1/A; NOP …
1 is bolded and the corresponding function A+=1/A is bolded to explain this somewhat more.
The initial A value is of course 0.
