13343	erf(NaN) and erfc(NaN) do not return NaN	Stéphane Laurent <laurent_step@…>	John Maddock	"Hello,

 It is expected that erf(NaN) and erfc(NaN) are NaN, but they are not:

{{{
#include <iostream>
#include <cmath>
#include ""boost/math/special_functions/erf.hpp""

int main(){
    std::cout << boost::math::erf(nan("""")) << ""\n"";
    std::cout << boost::math::erfc(nan("""")) << ""\n"";
    return 0;
}
}}}

Output:
{{{
1
0
}}}
