I'm totally with you. We write/run financial software for government. We MUST be correct to the penny. Our auditors absolutely check this stuff. We've never done $ math in JS, that just seems like a stupid place to do it. If it's in the browser, you can't trust anything that happens there anyways, as it runs client side, with almost zero security. We happily take $ input via JS on the client, but we just pass it through, and let the server(s) handle the actual math.
