template<class T >

auto c4::yml::Tree::to_arena ( T const & a ) -> typename std::enable_if<std::is_floating_point<T>::value, csubstr>::type

inline

serialize the given floating-point variable to the tree's arena, growing it as needed to accomodate the serialization.

Note: Growing the arena may cause relocation of the entire existing arena, and thus change the contents of individual nodes, and thus cost O(numnodes)+O(arenasize). To avoid this cost, ensure that the arena is reserved to an appropriate size using Tree::reserve_arena().
