30.4.7 The monetary category [category.monetary] General [category.monetary.general]

These templates handle monetary formats.
A template parameter indicates whether local or international monetary formats are to be used.
All specifications of member functions for money_put and money_get in the subclauses of [category.monetary] only apply to the specializations required in Tables 107 and 108 ([locale.category]).
Their members use their ios_base&, ios_base​::​iostate&, and fill arguments as described in [locale.categories], and the moneypunct<> and ctype<> facets, to determine formatting details.
