Re: IEEE 754 compliance

There are some resources for testing by Nelson Beebe at From what I understand, the main issues are handling of edge effects (underflow, overflow, divide by 0, etc.) where compilers may do some things different from the standard's prescription. There is, of course, an interaction here with hardware that may not provide ways to get at the bits (literally).

In my efforts to set up some Gnumeric test worksheets, I've tried to contact Beebe without success. He may have retired (I believe he is older than I, and I'm on the brink of retirement from teaching, but not from Gnumeric!) If there is interest, and in particular an example where IEEE754 may be important, I'll be happy to dig a bit. I was a corresponding (ie vote by mail) member of the IEEE 754 committee back in late 70s. Given the arcane detail, it will take a bit of review for me to get fully up to speed.
