- unsigned flag was not handled correctly for a number of mathematical funcions, which led to incorrect results - passing large values as the number of decimals to ROUND() resulted in incorrect results and even server crashes in some cases - reverted the fix and the testcase for bug #10083 as it violates the manual - fixed some testcases which relied on broken ROUND() behavior
