/** @file
The header <limits.h> defines several macros that expand to various limits and
parameters of the standard integer types.
The values given below shall be replaced by constant expressions suitable for
use in #if preprocessing directives. Moreover, except for CHAR_BIT and
MB_LEN_MAX, the following shall be replaced by expressions that have the same
type as would an expression that is an object of the corresponding type
converted according to the integer promotions. Their implementation-defined
values shall be equal or greater in magnitude (absolute value) to those
documented, with the same sign.
If the value of an object of type char is treated as a signed integer when
used in an expression, the value of CHAR_MIN shall be the same as that of
SCHAR_MIN and the value of CHAR_MAX shall be the same as that of SCHAR_MAX.
Otherwise, the value of CHAR_MIN shall be 0 and the value of CHAR_MAX shall
be the same as that of UCHAR_MAX.)
The value UCHAR_MAX shall equal 2^(CHAR_BIT - 1).
