Search for pi spigot algorithm. Here is a tiny C program from Jeremy Gibbon's Unbounded Spigot paper (due to Dik Winter and Achim Flammenkamp): a[52514],b,c=52514,d,e,f=1e4,g,h;main(){for(;b=c-=14;h=printf("%04d", e+d/f))for(e=d%=f;g=--b*2;d/=g)d=d*b+f*(h?a[b]:f/5),a[b]=d%--g;} This produces the first 15,000 digits concisely, but is obfuscated. If you need an unbounded number of digits, search out the spigot algorithm papers.
