isNaN should be available

[pcarbonn]

isNaN (and RealFloat) is missing in Relude.Base, while it is present in Base Prelude.

Is there any reason for that ? How can I fix it ?

[pcarbonn]

workaround: I import RealFloat from GHC.Float

import GHC.Float (RealFloat)

@pcarbonn Thanks for opening the issue! I don't see any particular reason why we shouldn't reexport RealFloat so I'm okay with reexporting this typeclass and isNaN function. Not sure about all functions, some names look common enough so they could conflict with something. As a safe solution I propose to reexport the following:

import GHC.Float (RealFloat (isNaN, isInfinite, isDenormalized, isNegativeZero, isIEEE))

Note, that in relude-0.5.0 all numeric-related functions were moved to the Relude.Numeric module so this reexport should go there:

Feel free to open pull request, I really appreciate this 🙂
