That's a fair statement. My understanding is also that 80-bit math is on 
the wrong side of the tradeoff simply because it's disproportionately 
slow (again I cite 
http://nicolas.limare.net/pro/notes/2014/12/12_arit_speed/). All modern 
ALUs I looked at have 32- and 64-bit FP units only. I'm trying to figure 
why. -- Andrei
