# In a ranking system, what value is conventional for scores/set/points quotient when the divisor is 0?

For instance, in volleyball they use set quotient or points quotient as tie-breakers. They are simply the result of sets/points won divided by sets/points lost. But what if sets/points lost is `0`? What is the conventional value that is used?

• If a team has conceded no points a tie break would not be necessary.

• @dly yes it would be necessary when comparing teams with no lost points May 22, 2019 at 9:39
• Then please provide an example where you would need it.

• @dly let's say we have a ranking system with wins > score quotient. If team 1 and team 2 both have won the same number of games they're tied, so we need to calculate the score quotient. But let's say the have no score against in any of their games, only score for. My question is then, how do you calculate the score quotient when the divisor is `0`? The post is not about deciding how the tie-breaker is resolved, but how a quotient is usually calculated in a ranking system when the divisor is 0. May 22, 2019 at 11:07
• If you have multiple pools that need to crossover according to a rank, or teams that need to be seeded for the next round, having multiple unbeaten teams or teams that have not conceded points.
