I see

 'is_string_like',
 'iscomplex',
 'iscomplexobj',
 'isfinite',
 'isfortran',
 'ishold',
 'isinf',
 'isinteractive',
 'isnan',
 'isneginf',
 'isposinf',
 'ispower2',
 'isreal',
 'isrealobj',
 'isscalar',
 'issctype',
 'issubclass_',
 'issubdtype',
 'issubsctype',

But apparently none of them test for a scalar number. That is a strange
functionality to be missing.
