A complete list of what types are acceptable for 'N' would be

This is specified fully in the template constraints:
if (isIntegral!N && isUnqual!N)
if ((isIntegral!N && !isUnqual!N) || isCheckedint!N)
The second overload simply forwards to the first, after applying
BasicScalar!(Unqual!N).
However, I recall that new users tend to get confused/intimidated
by template constraints, so I suppose I should add a prose
explanation to the docs, as well.
