+/** @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).
