Playing with template for FixedPoint naive implementation

great.cpp

#include <iostream>

template<std::size_t T>
struct FixedPoint {
    static constexpr int Size = T;
    int value;
    static_assert(Size < sizeof(value) * 8);
};

constexpr FixedPoint test(double d) {
    // some logic
}

template<std::size_t T>
void test(FixedPoint<T> point) {
    std::cout << point.Size << " " << point.value << " " << sizeof(point) << std::endl;
}

void test(FixedPoint<4> point) {
    std::cout << "I'm super optimized version for 4 bits" << point.Size << " " << point.value << " " << sizeof(point) << std::endl;
}

int main() {
    {
        FixedPoint<5> point;
        test(point);
    }

    {
        FixedPoint<4> point;
        test(point);
    }

    return 0;
}
