Summary

encode writes an amount with two decimal places. to_crc16_json checksummed Display of the float instead, so 10.5 was checksummed as 10.5 while the QR code contains 10.50. The CRC in the JSON did not match the code. The helper now uses the same two decimal places. 123.45 is unchanged.

Test plan

• cargo test --lib amount_with_one_decimal fails on master (the JSON CRC is 5A08, not the CRC of the QR code) and passes with this change.
• enconde_brcode and json_crc16 still pass.

Made with Cursor

Interesting catch, was cursor that identified it or was it you? Plain curiosity

Just need to run the ci which requires some updates

Cursor helped me spot it, and I checked the two-decimal CRC path before opening the PR. Happy to stand behind the change. No rush on the CI updates, and thanks for taking a look.

Today I should update the CI, then you can update your branch with main and CI should work
