Problem: cast to unsigned limited result to max signed bigint 9223372036854775808, instead of max unsigned bigint 18446744073709551615. Fix: don't use args[0]->val_int() when casting from a floating point number, use val() instead, with range checkings, special to unsigned data type. item_func.cc: Special handling of cast from REAL_RESULT to unsigned int: we cannot execute args[0]->val_int() because it cuts max allowed value to LONGLONG_INT, instead of ULONGLONG_INT required. count_distinct3.test: Getting rid of "Data truncated; out of range ..." warnings. cast.test, cast.result: Adding test case. ps.result: Fixing that cast from 6570515219.6535 to unsigned didn't round to 6570515220, and returned 6570515219 instead.
