implemented in C, ie. the code behind exp().

Any help would be much appreciated,

Assuming you want to implement this function by yourself, I would direct you to this site:

http://www.ualr.edu/~lasmoller/efacts.html

Here it is explained how one can approximate the value of e using series. One of the approximations:

e = 1+ 1/2 + 1/(2 x 3) + 1/(2 x 3 x 4) + 1/(2 x 3 x 4 x 5) + . . . - 01-05-2002GertFaller
#include <math.h>

Function: double exp (double x)

Example :

#include <stdio.h>

#include <math.h>

int main(void)

{

double y;

double x=2.37;

y = exp(x);

printf("%f\n",y);

getc(stdin);

return 0;

}
