Visit this for more details: www.russelltheprogrammer.com Collected from Sometimes you need to use exponencial or power , there is a library functions named pow() . http://russelltheprogrammer.com/ :: Source Some example in c++ given below: double pow( double x, int y ); // C++ only float pow( float x, float y ); // C++ only float pow( float x, int y ); // C++ only long double pow( long double x, long double y ); // C++ only long double pow( long double x, int y ); // C++ only Even you can also use pow() function as below method: double pow( double x, double y ); float powf( float x, float y ); long double powl( long double x, long double y ); Let’s See Some Code in C++: #include <bits/stdc++.h> using namespace std; int main() { double x = 7.0, y = 9.0, z; z = pow( x, y ); printf( “%.1f to the power of %.1f is %.1f\n”, x, y, z ); return 0; } Output: 7.0 to the power of 9.0 is 40353607.0 Source : http://russelltheprogrammer.com
