This is a random question about gasoline pricing conventions on this website and generally on the net. Generally, gas stations report prices out to three digits, and that digit is always 9 tenths of a cent (i.e., $3.199, $3.439, etc.) But most people who reference gasoline prices report only 2 digits. So are they rounding up or ignoring the extra 9 tenths of a cent?
Almost certainly ignoring. I know I do, although we shouldn't.
Over the last 3 weeks in canada, the "perma-9" at the end has disappeared, and it is now usually a non-nine number. Two stations at the same intersection were 1.227 and 1.225 a litre. The problem for me is because of traffic and the route home the 1.225 station is nearly impossible to get in or out of and you have to go a fair distance to easily make a u-turn. After having been stuck there I wouldn't consider visiting it for less than a 2 cent savings (most fillups for me are 40 liters, so that's about a dollar in the end). It's probably not cost effective given the likely small amount of gas to drive the extra quarter mile for an easy route, but we're emotional beings.
