DecimalValue has no method named

Error message

DecimalValue has no method named {method}

What it means

DecimalValue's call_method first tries attribute lookup via get_value; if no attribute matched, there is no fallback implementation for decimal-specific methods yet (the TODO notes they are unimplemented), so the call raises UnknownMethod naming DecimalValue and the requested method.

Solutions

1. Implement the needed decimal method (quantize, scale, etc.) in call_method
2. Use arithmetic filters/operators instead of method calls in templates
3. List available operations in the error to help template authors
