Hi, I saw somewhere (but don't remember exactly) that float96 is the equivalent double precision for 32-bit systems as float128 is for 64-bit systems, or something like this. My system is indeed 32-bit.
The 1.3 line (without float128, r9202) works fine. Thank you ! Séb :) Edward d'Auvergne wrote: > Hi, > > This might have something to do with the machine having a 32 bit > processor.
