Tried something like `"0\\.(\\d+)|(\\d+)\\.\\d+"`, and although it works, the
matched group is 1 or 2, depending on which part of the regexp matches, so we
can't always return group 1. An alternative would be to use two patterns and
don't use the OR inside the regexp, but in that case I think the current
implementation would be better. Thoughts?
