Split five cents three ways and one party gets the extra cent. It reads like a rounding bug. It is a decision nobody wrote down.
We work in minor units, floor the shares, then give leftovers to the largest remainders so the parts sum back exactly. And multiplication has to ask for a rounding mode with us, instead of quietly picking one. Probably few people on your side can say who gets that extra cent. https://shipmindlabs.com/c/bd7c04f1
