Defined in header <locale> template< class CharT, class InputIt = std::istreambuf_iterator<CharT> > class num_get; Class std::num_get encapsulates the rules for parsing string representations of numeric values. Specifically, types bool, unsigned short, unsigned int, long, unsigned long, long long, unsigned long long, float, double, long double, and void* are supported. The standard formatting input operators (such as cin >> n;) use the std::num_ge

Defined in header <locale> template< class CharT > class numpunct_byname : public std::numpunct<CharT>; std::numpunct_byname is a std::numpunct facet which encapsulates numeric punctuation preferences of a locale specified at its construction.

Defined in header <locale> template< class CharT > class numpunct; The facet std::numpunct encapsulates numeric punctuation preferences. Stream I/O operations use std::numpunct through std::num_get and std::num_put for parsing numeric input and formatting numeric output. The numbers that are supported by std::numpunct have the format described below. Here digit represents the radix set specified by the fmtflags argument value, thousands-sep and decimal-point are the r
