====== pow ======
<code cpp>
    float  pow(float  base, float  exponent);
    double pow(double base, double exponent);
    double pow(double base, int    exponent);
</code>

pow() returns base raised to the exp power.


===== cpp Sourcecode Example =====
<code cpp>
#include <iostream> /* including standard library */
#include <cmath> /* including math library */

using namespace std;
int main( void )
{
    //cout.setf(ios::fixed, ios::floatfield);
    cout.precision(8);

    cout << "4 raised to the 2nd power is: " << pow(4, 2) << endl;

    return 0;
}

</code>

==== output ====
     4 raised to the 2nd power is: 16
