Re: [Boost-users] Visual Studio C++ and Boost Multiprecision float128

Hi,

I use « Visual Studio Express 2013 for Desktop » to do my C++ programming.

When I come tu use Boost Multiprecision header « float128.hpp », I get the following message :

Fatal error C1189 : #error : « Sorry compiler is neither GCC, not Intel, don’t know how to configure this header. »

However, when I use Boost Multiprecision header « cpp_dec_float », it works well but much slowly.

I guess « float128.hpp » is faster : Am I right?

Is it possible to fix « float128.hpp » to suit C++ from Visual Studio?

No sorry: that header is a thin wrapper around the native type __float128 which msvc does not provide. On windows, you're limited to either GCC/Mingw or else Intel C++. John.
