Quick C++ Question

    Very simple question: I'm trying to use the pow method from cmath, but I getting an error:

    error C2873: 'pow' : symbol cannot be used in a using-declaration

    I'm sure it's something very simple that I've over looked. I've inported cmath, do I have to use something something like:

    using pow;

    or

    using cmath.pow;

    Thanks
    Ger...

    Worked for me anyways the using shouldn't really be necessary, try just using the pow function as normal, without any resolution operators... eg: 
    double x = pow ( 2, 3 ) ;

    When you include the cmath include, it normally just includes the old c math.h header file.
