std::pow gcem::pow divergence

[andrewkcorcoran]

Hi,

See below an example of difference in behaviour between std::pow and gcem::pow, this behaviour seems to continue for all pow(10, exponents <= -306

#include <gcem.hpp>
#include <cmath>
#include "fmt/format.h"

int main()
{
    fmt::print("{}\n{}\n", gcem::pow(10.0, -306), std::pow(10.0, -306));
}

Program stdout
9.999999999999994e-307
1e-306
