Edmund Landau (1877-1938). Gentlemen, we have not the slightest idea what this equation means, but we may be sure that it means something very important Benjamin Peirce (1809-1880). Well, I came to the same conclusion in 1977-1981, at Mikkeli Polytechnic Institute. |

This is a tiny C program from Xavier Gourdon (Jul 1999) to compute 9000 decimal digits of ℮ on your computer. |

main() {
int N=9009,n=N,a[9009],x;
while(--n)
a[n]=1+1/n;
for(;N>9; printf("%d",x))
for(n=N--;--n;a[n]=x%n,x=10*a[n-1]+x/n);
}
