text: the program goes like this:
  it should calculate the value of e^x by the series
  1+x+x^2/2!+x^3/3!...+x^n/n!
  when the user inputs a value , eps , which the program has to stop compute e^x when x^n/n<eps.
  I wrote 2 function , one calculating the factorial result (fact), and one calculates the value x^n/n! (monom).
  these functions works well, but the program keeps giving me 1 as result for e^x (or it gets stuck..)
  it seems that the problem comes from the condition monom (x,j)<eps, but I can't see why...
  can you guys help me? thanks a lot!can you guys help me? thanks a lot!Code:
  #include <stdio.h>
  #include <math.h>
  float fact (int);
  double monom (float x, int n);
  int main (void)
  {
  float x;
  printf ("please enter x value for e^x: ");
  scanf ("%f", &x);
  double exp=1;
  float eps;
  printf ("please enter delta: ");
  scanf ("%f", &eps);
  int j;
  for (j=1; monom (x,j)<eps; j++)
  exp+=monom (x,j);
  printf ("%f",exp);
  return 0;
  }
  float fact (int a)
  {
  float result=1;
  int i;
  for (i=1;i<=a;i++)
  result*=i;
  return result;
  }
  double monom (float x, int n)
  {
  return (pow(x,n)/fact(n));
  }
