Doing fuel tax - IFTA Reporting and rounding gallons.

Nope. Better stay in school.

By the odd-add rule 122.5 would round down to 122, but 123.5 would round up to 124. Note that there are 4 non-zero digits below 5 and 4 non-zero digits above 5. So 5 is exactly in the middle and there has to be an arbitrary rule for which way to round it. There is. The rule is to look at the previous digit. If the previous digit is odd you round the 5 up and if it's even you round it down.

 

What do you mean round up or down. I report exactly what I purchased. If it's 100.261 gals. that's what I report.

 

The ifta people don't want it done that way.
122.5 = 123.
122.49 = 122.

They only want to the nearest whole gallon. They don't want the remainder. Win some lose some.

 

Who told you that?

 

The ifta people when I filed my very first report lol
It came back with a reassessment and a page telling how they want it done. I don't have it anymore, that would of been in 2012. The jist of it: use whole gallons (litres for me).

 

any government form would want you to round off to the nearest dollar. ....... just listen to them and you can tell they have no cents
