Unfortunately, MINGW has problem with long double. It is a compiler bug,
which probably is not going to be fixed too.

Consult MINGW users mailing list if you want to more information on this
and to discuss it more.

Thanks
but when I use
cout << ld
It is OK

It isn't for much large values:


#include <limits>
#include <cfloat>
#include <iostream>


int main()
{
using namespace std;

long double ld= numeric_limits<long double>::max();

cout<<ld<<"\n";


ld= LDBL_MAX;

cout<<ld<<"\n";
}
