I've seen lists of errors for a specific program (never a list of multiple program's errors). In the past, I've done a search for the error number and see what pops up. Some of these lists contain both the number and the hex code, and some one or the other.
I've never seen a description of the error, or if there is, it's usually what appears on the screen, and offers no more insight. Usually documents explaining the error detail only the error itself, which offer much insight.
Hope this helps,
