[#bsl-vector-0aa7-emplace_back] = xref:bsl.adoc[bsl]::xref:bsl/vector-0aa7.adoc[vector<long double>]::emplace_back :relfileprefix: ../../ :mrdocs: Append to the end of this vector a newly created `value_type` object, constructed by forwarding `get_allocator()` (if required) and the specified (variable number of) `arguments` to the corresponding constructor of `value_type`. Return a reference providing modifiable access to the inserted element. If an exception is thrown (other than by the move constructor of a non‐copy‐insertable `value_type`), `*this` is unaffected. Throw `std::length_error` if `size() == max_size()`. This method requires that the (template parameter) type `VALUE_TYPE` be `move‐insertable` into this vector and `emplace‐constructible` from `arguments` (see {Requirements on `VALUE_TYPE`}). == Synopsis Declared in `<bslstl_vector.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- template<class...
