Clearly there are programmers who wish to be able to detect
certain exceptions, and POSIX allows programmers to
select that behavior.

 
Clearly, there is a committee which wanted to be able for people
to detect certain error conditions on a fine-grained level.
One assumes tht they did not consider the consequences.
 

Without exposing any internal discussions, it should be obvious to
anyone "versed in the field" that the ieee754 standard has some warts
and mistakes. It has been possible to correct very few of them since 1978.

I'm not throwing shade on the IEEE committe, they did quite a good
job, considering what they did and did not know.

What I was criticising was the comittee(s) which made errno handling
for functions like sin() and cos() mandatory, and put activating
it in a globel flag.
