alt Hacker NewsI'm sure there is something I don't know here, but how is working with integers "brittle"? The only issue I see is rounding down by default, not sure if that is even an issue or not. At any rate, it seems a lot less brittle than floats or bigdecimal style number classes.
The brittleness comes from the fact that the number of implied decimal digits per currency isn't always well-defined across all stakeholders and systems.
If you're only working in a single currency, there's usually no issue.
