Setting a subscription price like $19.99 would fail with "Invalid integer 1998.9…999999999998" from the Stripe API. Due to IEEE-754 floating point arithmetic, `parseFloat("19.99") * 100` produces `1998.9999999999998` instead of `1999`. This non-integer value is then sent directly to Stripe which rejects it. Wrapping the multiplication in `Math.round()` ensures the result is always a proper integer before being stored as `unit_amount`. https://meta.discourse.org/t/393466
