    What is the binary type? Integer? Floating point? By decimal, do you mean a decimal string?

        Well I can only count zero and not zero.... so octal is out of my league.... :-)

        Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert. Sometimes it takes a lot of work to be lazy

              #include #include #include using namespace std; int main(void){ string bi = "1010"; //binary int result= 0; for (int i = 0; i< bi.size(); i++){ if (bi[i] == '1'){ result += pow((double)2,(double)bi.size()-i)/2; } } cout << result << endl; return 0; } that should work
