Sizes of integral types

This header defines constants with the limits of integral types for the specific system and compiler implementation used.

name	expresses	value*
`CHAR_BIT`	Number of bits for a `char` object (byte)	`8` or greater
`SCHAR_MIN`	Minimum value for an object of type `signed char`	`-127` or less
`SCHAR_MAX`	Maximum value for an object of type `signed char`	`127` or more
`UCHAR_MAX`	Maximum value for an object of type `unsigned char`	`255` or more
`CHAR_MIN`	Minimum value for an object of type `char`	either `SCHAR_MIN` or `0`
`CHAR_MAX`	Maximum value for an object of type `char`	either `SCHAR_MAX` or `UCHAR_MAX`
`MB_LEN_MAX`	Maximum number of bytes in a multibyte character, for any locale	`1` or greater
`SHRT_MIN`	Minimum value for an object of type `short int`	`-32767` or less
`SHRT_MAX`	Maximum value for an object of type `short int`	`32767` or greater
`USHRT_MAX`	Maximum value for an object of type `unsigned short int`	`65535` or greater
`INT_MIN`	Minimum value for an object of type `int`	`-32767` or less
`INT_MAX`	Maximum value for an object of type `int`	`32767` or greater
`UINT_MAX`	Maximum value for an object of type `unsigned int`	`65535` or greater
`LONG_MIN`	Minimum value for an object of type `long int`	`-2147483647` or less
`LONG_MAX`	Maximum value for an object of type `long int`	`2147483647` or greater
`ULONG_MAX`	Maximum value for an object of type `unsigned long int`	`4294967295` or greater

* the actual value depends on the particular system and library implementation, but shall reflect the limits of these types in the target platform.
