Description
According to Programming languages - C++
Digit grouping is checked. That is, the positions of discarded
separators is examined for consistency with
use_facet<numpunct<charT> >(loc ).grouping()
BUT what if there is no separators at all and grouping()
is not empty? Well, we have no extraced separators, so we
won`t check them for consistency. This will allow us to
work with "C" locale from other locales.
Moreover, looks like some implementations of STL use this approach.
