F.10.8.2 The nan functions has:
2 The returned value is exact and is independent of the current rounding direction mode.
I read that as meaning no floating-point exceptions are raised by the nan() function.
However, I have found that (at least) glibc raises FP_INVALID if the string passed
to nan() has lots of valid characters. Is that a bug in glibc?
