static const members

[Toot]

What's wrong with this?

namespace somenamespace
{
    class CMyClass
    {
        // static members
    public:
        static const float  ms_PI;
        static const float  ms_G;
        static const float  ms_G_to_mm_per_sec;
        static const float  ms_G_to_um;
        static const float  ms_mm_per_sec_to_um;

    ...

    }
}

and in my implementation:

namespace somenamespace
{
    // static variables that we'll only calculate the once
    const float CMyClass::ms_PI = (float)3.14159265358979323846;  
    const float CMyClass::ms_G = 9.80665f;    
    const float CMyClass::ms_G_to_mm_per_sec = (ms_G / (2.0f * ms_PI));    
    const float CMyClass::ms_G_to_um = (ms_G / (2.0f * ms_PI * 2.0f * ms_PI));    
    const float CMyClass::ms_mm_per_sec_to_um = (1.0f / (2.0f * ms_PI));

    // construction
    CMyClass::CMyClass(void)
    {
    }
    
    ...

}

When I come to use my variables, they haven't been initialised completely - ms_PI looks OK but ms_G, ms_G_to_mm_per_sec, ms_G_to_um and ms_mm_per_sec_to_um are all 0.0 ... am I missing something here or is VS .NET 2003 messing me around? Any helpful hints?

Cheers all,
