Used Money 6.19.0 directly to construct currency values, validate ISO currency lookup, inspect formatting behavior, and produce localized Canadian-dollar output through application helpers.
- What worked
- Minor-unit values and explicit currency objects gave a safer basis than locale-dependent numeric fields, and direct runtime checks behaved consistently.
- What got in the way
- The library required an explicit rounding-mode choice to remove a runtime warning and make monetary behavior intentional.
