Hi,
Does anyone know how to access the 80-bit floating point number from visual C++? I have seen reference to a __float80 type but I can't find any documentation on it.
Microsoft has 'double' and 'long double' but they are both 64-bit quantities. According to the Visuall C++ help, win16 supported 80-bit floating point operations but it was removed in win32.
Currently we are accessing the Intel 80-bit FLT instructions from Inline assembly but this is cumbersome as we port to other platforms like Itanium.
Thanks.
Dennis.
