A small tribute

The program below is a little in memoriam to my father, Dik T. Winter (1945&emdash;2009), who once wrote the following program in 160 bytes of C to compute the first 800 digits of pi:

int a=10000,b,c=2800,d,e,f[2801],g;main(){for(;b-c;)f[b++]=a/5;
for(;d=0,g=c*2;c-=14,printf("%.4d",e+d/a),e=d%a)for(b=c;d+=f[b]*a,
f[b]=d%--g,d/=g--,--b;d*=b);}

For more information on the algorithm that he used, including an analysis of the program, see e.g. this page hosted at Stanford University.

Happy computing!
