MySQL translator (mysql, mysql5) - convert( ..., float [double]) uses "+ 0.0" construction

convert(... , float) and convert(..., double) functions use for conversion "+ 0.0". But if the result is used in the more complex expression, translator does not take into account priority of the operators.

Query: SELECT StringKey, (convert(StringKey, float)+(-3)) AS StringKeyPlusNeg3, (convert(StringKey, float) - (-3)) AS StringKeyMinusNeg3, (convert(StringKey, float)*(-3)) AS StringKeyTimesNeg3, (convert(StringKey, float)/(-3)) AS StringKeyDivNeg3 FROM table WHERE IntKey == 1 ORDER BY StringKey

Result: 1 | -2 | 4 | 1 | 1

Source-specific query: SELECT g_0.STRINGKEY AS c_0, (g_0.STRINGKEY + 0.0 + -3.0) AS c_1, (g_0.STRINGKEY + 0.0 - -3.0) AS c_2, (g_0.STRINGKEY + 0.0 * -3.0) AS c_3, (g_0.STRINGKEY + 0.0 / -3.0) AS c_4 FROM smalla AS g_0 WHERE g_0.INTKEY > 0 AND g_0.INTKEY <= 10 ORDER BY c_0
