This program is not giving me any values when i enter a number. For example 0.5 gives nothing but zeros. This is a Taylor Series Convergence Program but no luck getting any values for e^x, the sum or the difference. Please help. #include #include #include #include long int factorial (int n); int main() { double x; double ex; double diff; printf ("Enter the value of x = "); scanf("%lf", &x); while (x < 0) { printf ("Please enter the value of x greater than 0, x = "); scanf("%lf", &x); } printf ("#iter\t e^x\t\t\t sum\t\t\t diff "); double s = 0; int i = 0; do { printf ("%-4d", i+1); ex = exp(x); printf ("%13.6lf\t\t", ex); s = s+((float)pow(x,i)/(float)factorial(i)); printf ("%10.6lf\t\t", s); diff = ex-s; printf ("%12.8lf", diff); i++; printf (" "); } while (diff > FLT_EPSILON); printf ("The number of Iterations required for convergence is : %d ",i); //system ("pause"); return 0; } long int factorial (int n) { if (n <= 1) { return(1); } else { n = n*factorial(n-1); } return(n); }
