48x98 is exactly that dimension (i..e after planing of the lumber). Well, +/- 1 mm of tolerance/shrinkage due to drying.
It goes by the name "two four" here as well informally due to long tradition (and yes, I once did wonder why 2-by-4 is smaller than 2 by 4 inches and looked it up), but you will not see it written anywhere, in writing it is always in mm after planing.
The oral words for lumber dimensions before planing is the only context as an adult I have met inches except in US.
