Hi, I've come to know that gcc uses the x87 standard of 80 bit long doubles. Is there a version that uses all 128 bits for long double? Or perhaps could you suggest an alternate compiler that does so? I have an AMD 64 cluster and would really like to use 128 bit long doubles for some very large datasets I am testing. Thank you very much. Usman Roshan Assistant Professor Department of Computer Science New Jersey Institute of Technology http://www.cs.njit.edu/usman/
