This is valid C, not even a coding style error, and this is a rather common use of unsigned types, and sometimes necessary to avoid undefined behavior (think of "-LONG_MIN", which needs to be done in unsigned arithmetic, e.g. "- (unsigned long) LONG_MIN", because -LONG_MIN is not representable as a signed long). -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) _______________________________________________ gmp-bugs mailing list [email protected] https://gmplib.org/mailman/listinfo/gmp-bugs
