Extended version of power function that can work for float x and negative y
#include <bits/stdc++.h> NEW_LINE using namespace std ; float power ( float x , int y ) { float temp ; if ( y == 0 ) return 1 ; temp = power ( x , y / 2 ) ; if ( y % 2 == 0 ) return temp * temp ; else { if ( y > 0 ) return x * temp * temp ; else return ( temp * temp ) / x ; } }
