The corrected version is more recognizable to me as "round"; I believe this is a fairly common pattern in code that needs to round or align to powers of two. However, I'll agree that it is perhaps overly clever. I recently wrote some code that used this pattern, except I had remembered it wrong and wrote something like: padded_size := (size + 2047) & ~2048 (2048 instead of 2047.) Luckily it was caught in code review, but it's worth being a bit more explicit; our solution (aside from fixing the number) was to add ASSERT(padded_size % 2048 == 0) so that it was clear what the code was trying to do.
