We have a winner! (very nicely done!)
Thank you, thank you!
Are the details of the Pentium 1's FDIV problem
on-topic?
I don't know, but I don't know a thing about them - well, except that I
can dig out a specific test case from certain open-source OS kernels,
which auto-detect it at boot time.
I wish that down-sizing hadn't taken away teaching
the computer math
class!
It's not classes that I learnt this stuff from. It's from hacking
around with it for umpty-ump years. (For example, I once did a PDP-11
emulator that did floating point, and getting the floating point right
without depending on the host's floating-point implementation demanded
a fair bit of research and thought.)
