localeconv - get numeric formatting information
#include <locale.h> struct lconv *localeconv(void);
The localeconv() function returns a pointer to a
struct lconv for the current locale. This structure is shown in locale(7), and contains all values associated with the locale categories LC_NUMERIC and LC_MONETARY. Programs may also use the functions printf(3) and strfmon(3), which behave according to the actual locale in use.
The printf(3) family of functions may or may not honor the current locale.
