change = {status: "INSUFFICIENT_FUNDS", change: []};
I was expecting this uncommented test to return insufficient funds
as it is I’m passing 3 out of the 6 test
but due to how javascript handles decimals
I’m afraid I’ve lost scope of where I have scaled up or down 2 digits
and where it affects a conditional comparison
