From cppreference.com
< cpp‎ | header

This header was originally in the C standard library as `<limits.h>`.

This header is part of the type support library, in particular it's part of the C numeric limits interface.

### Macros

CHAR_BIT | number of bits in byte (macro constant)
MB_LEN_MAX | maximum number of bytes in a multibyte character (macro constant)
CHAR_MIN | minimum value of char (macro constant)
CHAR_MAX | maximum value of char (macro constant)
SCHAR_MIN SHRT_MIN INT_MIN LONG_MIN LLONG_MIN (C++11) | minimum value of signed char, short, int, long and long long respectively (macro constant)
SCHAR_MAX SHRT_MAX INT_MAX LONG_MAX LLONG_MAX (C++11) | maximum value of signed char, short, int, long and long long respectively (macro constant)
UCHAR_MAX USHRT_MAX UINT_MAX ULONG_MAX ULLONG_MAX (C++11) | maximum value of unsigned char, unsigned short, unsigned int, unsigned long and unsigned long long respectively (macro constant)
