The isnumber() function behaves similarly to isdigit(), but may recognize additional characters, depending on the current locale setting.
The value of the argument must be representable as an unsigned char or the value of EOF.
The _l-suffixed versions take an explicit locale argument, whereas the non-suffixed versions use the current global or per-thread locale.
