Interpret characters from the half‐open iterator range denoted by the specified `begin` and `end`, generate a decimal floating‐point number and store it into the specified `value`. During conversion the formatting flags of the specified `str` (`str.flags()`) are obeyed; character classifications are determined by the `bsl::ctype` while punctuation characters are determined by the `bsl::numpunct` facet imbued to the `str` stream‐base. Use the specified `err` to report back failure or EOF streams states. For further, more detailed information please consult the section [lib.facet.num.get.virtuals]of the C++ Standard. Note that for the conversions to the `Decimal32`, 64 and 128 types the conversion specifiers are %Hg, %Dg and %DDg, respectively. Also note that these (possibly overridden) `do_get` virtual function are used by every formatted C++ stream input operator call (`in >> aDecNumber`).
