All numeric operators and functions on integer, floating point and DECIMAL values now throw an 'out of range' error rather than returning an incorrect value or NULL, when the result is out of supported range for the corresponding data type. Some test cases in the test suite had to be updated accordingly either because the test case itself relied on a value returned in case of a numeric overflow, or because a numeric overflow was the root cause of the corresponding bugs. The latter tests are no longer relevant, since the expressions used to trigger the corresponding bugs are not valid anymore. However, such test cases have been adjusted and kept "for the record". mysql-test/r/func_math.result: Added test cases for bug #8433. Updated results of the test case for bug #31236. mysql-test/r/func_misc.result: Streamlined test cases. mysql-test/r/func_test.result: Streamlined test cases. mysql-test/r/select.result: Streamlined test cases. mysql-test/r/sp.result: Streamlined test cases. mysql-test/r/strict.result: Streamlined test cases. mysql-test/r/type_newdecimal.result: Streamlined test cases. mysql-test/suite/sys_vars/r/sql_slave_skip_counter_basic.result: Streamlined test cases. mysql-test/suite/sys_vars/t/sql_slave_skip_counter_basic.test: Streamlined test cases. mysql-test/t/func_math.test: Added test cases for bug #8433.
