GFG EXPONENTIAL CALCULATION EFFICIENTLY!

28 Jan 2022

Way to calcuate e^x efficiently… 💪🏼 => Taylor Series

#include <bits/stdc++.h>
using namespace std;
 
float exponential(int n, float x) {
    float sum = 1.0f;
    for (int i = n - 1; i > 0; --i )
        sum = 1 + x * sum / i;
    return sum;
}
 
int main() {
    int n = 10;
    float x = 1.0f;
    cout << "e^x = " << fixed << setprecision(5) << exponential(n, x);
    return 0;
}
