Sinacore Rounding 

In high school physics, when answers do not come out to the number desired, Sinacore Rounding takes place.

i divided and had 7.01x10^-14. Danny P's answer was 8.45x10^-12, so i used Sinacore Rounding so we would have the same answer.

sidnaceous 

Head Moderator At Tim Buckely's CtrlAltDel webcomic.

Often critized for taking a 'nazi' approach to forum members, particularly during the infamous RoMicide.

Also knows as Sid, he is widely respected, and known, to be one of the top moderators on the Internet.

Though a common hate figure, his devotion and drive cannot be doubted.

Sidnaceous banned me again. He's so strict!
