class std::num_get< _CharT, _InIter >"Primary class template num_get\&. 

This facet encapsulates the code to parse and return a number from a string\&. It is used by the istream numeric extraction operators\&.
.PP
The num_get template uses protected virtual functions to provide the actual results\&. The public accessors forward the call to the virtual functions\&. These virtual functions are hooks for developers to implement the behavior they require from the num_get facet\&.

Numeric parsing\&. Parses the input stream into the bool \fIv\fP\&. It does so by calling num_get::do_get()\&.
