Querydsl: Round(x) Function

[Ghalleb]

I saw there is a round() function that return the closest int from the numeric variable.
But there is no round(x) function that would return the numeric value with x decimal.

For example:

select round(192.4525, 2) -> 192.46
select round(2.3246, 2) -> 2.32 

Some doc here:

How well is this supported in other SQL dialects?

There is the same function in MySql:

Also in Oracle:
