Is there a floor function in Mongodb aggregation framework?

Question

I try to do some integer math in mongodb and have some problems. Is there a way to round doubles up or down in the mongo db aggregation framework?

Answer 1

As per the comment from Stennie, the floor and ceiling methods are not supported.

And as per my comment above, the best solution that I could find was just doing an operation that looks like: (num-mod(num,1)) which should yield the same result as the floor function.
