Topic: ASCII85Decode Filter

I have a doubt on ASCII85Decode. I read PDFSpec 1.3 Manual on ASCII85Decode section, and i am confused.

In ASCII85Decode how to solve the problem of last partial 5-tuple. If I get 3 characters in the last partial 5-tuple, i don't know shall i name it c1,c2,c3 or c3,c4,c5 and make others zero and decode it. Or, what happens in encoding in case of last partial 4-tuple.

Simply put, which char comes first in a given group of 5 chars. Is it c1 or c5?

Where can I get more info on this topic? Please help.
Thanks in advance.
