Alexey Kopytov afb2b6de68 Fix for bug #43432: Union on floats does unnecessary rounding ... UNION could convert fixed-point FLOAT(M,D)/DOUBLE(M,D) columns to FLOAT/DOUBLE when aggregating data types from the SELECT substatements. While there is nothing particularly wrong with this behavior, especially when M is greater than the hardware precision limits, it could be confusing in cases when all SELECT statements in a union have the same FLOAT(M,D)/DOUBLE(M,D) columns with equal precision specifications listed in the same position. Since the manual is quite vague on what data type should be returned in such cases, the bug was fixed by implementing the most 'expected' behavior: do not convert FLOAT(M,D)/DOUBLE(M,D) to anything else if all SELECT statements in a UNION have the same precision for that column.		2009-03-27 13:12:50 +03:00
