Absolutely. or at least to the same extent that finite things can be understood as 'absolute'.
To make it more explicit, what I think you mean by 'absolute' is 'wholly knowable' or complete in knowledge'.
Let's limit ourselves simply to number-like things. I'll presume that you accept finite integers as 'absolute' in this sense.
So what about a rational number, say 1/3? In terms of your question it is the solution to the simple equation "3 x = 1". Is it 'absolute'? I think you'd think so because it is the ratio of two finite numbers. But in some calculations, you may need to know its decimal representation, which is 0.333333..., an infinite sequence of threes. This representation is 'absolute' because we know that any particular digit can be finitely described (namely it's always 3).
What about 1/7? An exercise for the reader...it's not as simple as 1/3, but still has the same property, we can easily know any particular digit no matter how far out.
Rather than try to continue this reasoning for more complicated numbers (which would similarly work for irrationals like sqrt(2) and the mentioned pi, I think the point is made with rationals with no-terminating decimal representations: there exist infinite objects which are 'absolute'.
