I understand the left shifting of the Gigawords value and the subsequent 'or'-ing of the Acct-Input-Octets value to produce one 64-bit value. The part that confuses me is the repeated occurrence of the ':-0' at the end of each variable. What is the purpose of this? I have seen it on other pages used with other variable substitutions. I have also seen the above Gigawords entry done without the ':-0' [only once though]. I would rather understand the purpose behind the entry rather than blindly copying it.
