Round to one decimal place:
5.55 ==> 5.6
5.45 ==> 5.4

I don't think I was familiar with this method (Banker's method if I recall correctly) until Richard Nelson's talk about rounding methods at HHC 2018.

I think it's popular with statisticians since it tends to reduce rounding error when given a large sample population.
