> Project: Phoenix
> Issue Type: Bug
>Affects Versions: 4.6.0
>Reporter: Kevin Liew

> Labels: function, phoenix
> Fix For: 4.8.0

>
> ANSI SQL specifies that
> {quote}If SUM is specified and DT is exact numeric with scale
> S, then the data type of the result is exact numeric with
> implementation-defined precision and scale S.
> ...
> If DT is approximate numeric, then the data type of the
> result is approximate numeric with implementation-defined
> precision not less than the precision of DT.{quote}
> However, when summing integer types (first operand) with float or double
> (second operand), Phoenix returns the value with the same data type as the
> first operand.
> Doing a sum with the first operand being a FLOAT or DOUBLE will return a
> DECIMAL with a fixed scale of 4.
> Doing any multiplication or division will also result in a DECIMAL with scale
> 4.
> In all of the cases outlined above, the return data type does not meet the
> ANSI standard.
