    You don't need any.

    Decimal numbers are 0-9,
    Hex: 0-9 then A-F

    Can't think of a simpler algorithm than that!

    Try it out, you might suprise yourself.
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }
