Losing cents is because somebody didn't use Decimal for currency. And that's just flat out malfeasance--possibly even regulatory malfeasance.
Double entry is irrelevant, here.
I love the "use crypto" to fix the problem suggestion. LOL!
It's kind of poignant since crypto has given me a fantastic club to beat executives over the head with whenever they want to do stupid handling of money. Since crypto has so many decimal places, you break dumbass floating point handling of money immediately and irretrievably for way more than just "a couple cents". Your CFO starts jumping up and down really excitedly about handling money properly when he has to worry about a rounding error forcing him to compensate a Bitcoin price jump/crash.
It could be rounding issues as well (roundings do not all cancel out), or having to divide an even amount unevenly (how do you pay $10 in three "equal" installments?) Even with infinite decimal precision there will be special handling involved.
