                  2 %INTMAX Largest positive integer value.
                  3 %   X = INTMAX is the largest positive value representable in an int32.
                  4 %   Any value that is larger than INTMAX will saturate to INTMAX when
                  5 %   cast to int32.

                  7 %   INTMAX('int32') is the same as INTMAX with no arguments.
                  8 %
                  9 %   INTMAX(CLASSNAME) is the largest positive value in the integer class
                 10 %   CLASSNAME. Valid values of CLASSNAME are 'int8', 'uint8', 'int16',
                 11 %   'uint16', 'int32', 'uint32', 'int64' and 'uint64'.
