Set locale to user-preferred locale except std::locale::numeric

Date, messages and currency should formatted in user default settings, but numbers should be parsed and printed in the "C" locale. This is the way we do it now:
setlocale(LC_NUMERIC, "C");
//
// this is supposed to set the current locale but C locale for numeric and messages. See https://msdn.microsoft.com/de-de/library/1w3527e2.aspx
std::locale loc(std::locale::empty());
std::locale loc1(loc, std::locale::classic(), std::locale::numeric);
std::locale::global(loc1);
Is this the correct way to set such a locale? It looks somewhat cumbersome. Also, is there a reason/case/use in setting the locale both via C's setlocale() and CPP's std::locale::global()?

How about changing the order, so you set the "global" locale first and then change the single bit you want to be different?

@Someprogrammerdude, do you mean firststd::locale::global()thensetlocale(LC_NUMERIC, "C")? Actually this was a bit a part of the question. Do these both work on the same locale? Or are the C locale and the CPP locale two different locales?
