I'd wish to make it clear that I referred to this statement:

An my understanding was:

So we have:

[Please correct me if the following statement is wrong.] "StrictMath" must
reproduce the _same_ results on any JVM.
Then, to be replacement, "FastMath" must reproduce those _same_ (i.e. same
as "StricMath") results.
Is that the case?

If "FastMath" is as fast (or faster), for all methods, than "Math" (while
being as accurate), then it is a replacement of "Math".
Is that the case? [Luc already answered "Yes" to that question.]
