Mm. PI.

[myrathi]

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);}
pi to 800 digits. In 160 characters of code. Woo! 0_o

Well

Missing the decimal point of course,
and the last digit is the correct one but where you to finish your number there you'd round up.

Still fairly impressive,
beats the question though ... How did anyone find that out???

Oh well.

(P.S.: And yes I did get the C compiler out and checked it ... sad I know)

Re: Well

Yeah. To be specific, it should really insert the '.' and suffix '...' or something.

But still. Woo.

How did anyone work it out?

That's the question.

It was an "obfuscated C" competition entry some time back. These people are just scary intelligent. :>
