That's an understatement.
I remember it getting rehashed over and over again in various USENET
groups 35 years ago when when the VAX 11/780 BSD machine on which I
read news exchanged postings with peers using a half-dozen dial-up
modems and UUCP.
One would have thought it would be a time-saver when David Goldberg
wrote "the paper" in 1991, and you could tell people to go away and
read this:
https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html
https://www.itu.dk/~sestoft/bachelor/IEEE754_article.pdf
It didn't help.
Every fall, the groups were again full of a new crop of people who had
just discovered all sorts of bugs in the way <software/hardware>
implemented floating point, and pointing them to a nicely written
document that explained it never did any good.
