Research direction
This issue requests an AMP example demonstrating currency conversion using amp bind with mathematical operators and dynamic data from amp state. The repository is deprecated and merged into amp.dev, so first confirm if the example is still relevant. If so, review existing amp bind examples in the repository for patterns, then implement a sample that allows users to switch between currencies (e.g., USD to EUR). The conversion rates could be fetched from a public API via amp state's src attribute or hardcoded for simplicity. Ensure the example includes clear comments and follows AMP validation.
