I was looking at the code, and I think this is a more general problem with
decimal widening. The same problem exists for least, and other functions.
```
scala> sql("select least(0.1, 0.01)").collect()
org.apache.spark.sql.AnalysisException: cannot resolve 'least(CAST(0.1 AS
DECIMAL(1,1)), CAST(0.01 AS DECIMAL(2,2)))' due to data type mismatch: The
expressions should all have the same type, got LEAST
(ArrayBuffer(DecimalType(1,1), DecimalType(2,2))).; line 1 pos 7
```
