How would this handle Canadian guidelines for dealing with cents in cash, where you round to the nearest 5c [1]?

    Amounts ending in 1 cent and 2 cents are rounded down to the nearest 10 cents;
    Amounts ending in 3 cents and 4 cents are rounded up to the nearest 5 cents;
    Amounts ending in 6 cents and 7 cents are rounded down to the nearest 5 cents;
    Amounts ending in 8 cents and 9 cents are rounded up to the nearest 10 cents;
    Amounts ending in 0 cent and 5 cents remain unchanged.

EDIT: I think if you send 12 cents,

    send [CADCASH/2 12] ( source = @user1 destination = @user2 )

It should result in sending 10 cents.

    "postings": [{"source": "user1",
                  "destination": "user2",
                  "amount": 10,
                  "asset": "CADCASH/2"}]

Can this happen?

Well that's definitely a good puzzle. I've tried to model it for a bit, but it indeed looks like we'd need to add something to the language to make it possible at all! Thanks for bringing this up.

Same thing with income tax brackets. You need conditional logic.

  For this particular case, I would say that tax-brackets sort of logic can be expressed in the destination block with ordered destinations.
  For example, you could have something like this:
  send [USD/2 *] ( source = @users:1234 destination = { // first $1000 are taxed at 10% max [USD/2 100000] to { 10% to @taxes remaining kept } // Anything above that is, taxed at 20% remaining to { 20% to @taxes remaining kept } } )
  (You can test it on the playground, you'll just want to feed the "users:1234" account with an initial balance in the input section)

The rules listed (1,2,6,7 round down; 3,4,8,9 round up). AFAIK these are also the official Eurozone cash rules for countries that choose not to circulate 1 and 2 eurocent coins. (Altho of course, electronic transactions are exact to the penny.) So you might want to cover this use case.

I’m assuming there are guidelines as to when this conversion happens and how often. Must make itemized invoices lots of fun. Specially when you have returns or cancellations
