Detailed Description

template<typename T>
struct Dune::IsIndexable< T >

Whether this type has a value of NaN.

Deprecated:

has_nan is deprecated, use Dune::HasNaN instead

Internally, this is just a forward to std::is_floating_point<T>. Type trait to determine whether an instance of T has an operator[](I), i.e. whether it can be indexed with an index of type I.

Warning

Not all compilers support testing for arbitrary index types. In particular, there are problems with GCC 4.4 and 4.5.
