So what is fast-math?

It's a compiler flag or option that exists in many languages and compilers…

So what does it actually do? Well, as the name said, it makes your math faster.
That sounds great, we should definitely do that!

I mean, the whole point of fast-math is trading off speed with correctness. If
fast-math was to give always the correct results, it wouldn't be fast-math, it
would be the standard way of doing math.

ye olde "why don't they make the whole airplane out of
the black box"

i guess the retort is: if it's a tradeoff, why does "fast" get
to be in the name

like it's a tradeoff but only the upside gets in the name. i
mean maybe that's appropriate

could be hasty-math
