12075,denorm_min is zero for float128,Ruslan <b7.10110111@…>,John Maddock,"The following program demonstrates the bug:
{{{
#include <iostream>
#include <limits>
#include <boost/multiprecision/float128.hpp>

boost::multiprecision::float128 typedef binary128;
int main()
{
    std::cout << ""boost "" BOOST_LIB_VERSION << ""\n"";
    std::cout << ""boost denorm_min: "" << std::numeric_limits<binary128>::denorm_min() << ""\n"";
    __float128 trueDenormMin=0;
    *reinterpret_cast<char*>(&trueDenormMin)=1; // craft the denormal manually
    std::cout << ""true denorm_min:  "" << binary128(trueDenormMin) << ""\n"";
}
}}}

Its output is
{{{
boost 1_60
boost denorm_min: 0
true denorm_min:  6.47518e-4966
