Please review this doc-only enhancement which links the word _equivalent_ in
`Float.NaN` and `Double.NaN` constant field descriptions to the floating-point
equivalence discussion in `Double`.
> It is equivalent to the value returned by{@code
> Float.intBitsToFloat(0x7fc00000)}.
For readers not well-versed in floating point, it may not be immediatly clear
what _equivalent to_ means here.
The smallest improvement I could think of is to simply make the word
`equivalent` a plain link to the floating-point equivalence discussion in the
class description of `java.lang.Double`.
Verification: This is a doc-only change. I ran `make docs` and verified that
the links resolve.
