Hi,

I've had a bug reported where attempting to register Vec4<int> fails in Windows (Visual Studio 15 and Visual Studio 19).

It appears the problem is a missing implementation of std::isinf(int). I see this method in math::Tuple which uses math::isFinite() that correctly handles integer types:

bool isFinite() const {
    for (int i = 0; i < SIZE; ++i) {
        if (!math::isFinite(mm[i])) return false;
    }
    return true;
}

However, this one uses std::isinf():

bool isInfinite() const {
    for (int i = 0; i < SIZE; ++i) {
        if (std::isinf(mm[i])) return true;
    }
    return false;
}

Any issues with fixing isInfinite() and isNan() in the same way using new math::isinfinite() and math::isnan() methods?
