test/src/lib/LibDecimalFloat.inv.t.sol (3)
5-5: Properly introducing the Float structThese changes correctly import the
Floatstruct and enable the use of library functions on it with theusingdirective. This is a well-structured approach to implementing the new float struct pattern.Also applies to: 9-9
11-17: Good implementation of external wrapper functionsThe overloaded function pattern here is well implemented:
- First overload accepts traditional raw integer parameters
- Second overload works with the new
FloatstructThis approach maintains backward compatibility while introducing the new struct-based API.
20-31: Well-structured test for memory operationsThe test function properly validates that both implementations (raw integers vs. Float struct) produce the same results. The try-catch pattern effectively handles both success and error cases:
- For successful calls, it verifies that both implementations return the same values
- For failing calls, it verifies that both implementations fail with the same error
This is a robust approach to ensure consistent behavior.
