I think either of the styles you have given (and the ones posted)
are reasonable. I take many things into consideration, such as
readability, logic flow, readability by others, speed, extensibility, 
whether the code is scientific in nature or manipulates text, and so on.

Realizing that I am departing from what others have said, I like the
second case best because of its conciseness (I like that in my numeric
code). I would only alter it if performance was a concern.
