I don’t know what it should be but i think the right approach is to reduce whatever bias you introduce by rounding to a minimum. ie. if you ways round up at .5 and you get a lot of digits with .5 in them, it’s easy to see how you can cause a significant financial loss. eg. 1million transactions.
there may not be much of an issue between 0.01 pesewas and 0.02 pesewas in most cases but for some others, it’s important that you get it right. eg. quoting bandwidth cost which might be quoted as 0.05Gp per kilobyte.
there are rounding algorithms like bankers algorithm or random rounding you can experiment with.

how do you decide to run down or up? i though in finance, one runs down whenever possible. eg. if i enter 10150-10190 i get GH₵1.02, but for 10100-10140 i get GH₵1.01
