Not really, is it? x86 processors have internal 80 bit fp registers
but anything that has to go out to memory gets truncated to 64 bits.
Since a high-level like Fortran can't/shouldn't make assumptions
about where in the system a fp value is, an 80 bit kind really isn't
feasible here. Are there systems that actually support 80 bit fp
numbers fully?
