test/src/lib/op/math/LibOpMul.t.sol (1)
59-59: Good practice: UsingassertTrueinstead ofassertin tests.This change correctly uses the testing framework's assertion method instead of Solidity's
assert, which is more appropriate for test validation.src/lib/op/LibAllStandardOps.sol (6)
58-58: LGTM: Import updated to new less-than implementation.The import correctly references the new floating-point based
LibOpLessThanreplacing the integer-basedLibOpLessThanNP.
224-224: Improved clarity: Using boolean terminology in metadata.The description now correctly uses "true"/"false" instead of numeric "1"/"0", which better reflects the boolean nature of the comparison operation.
434-435: Operation enabled: Less-than operand handler uncommented.The less-than operation is now properly enabled in the operand handler array by uncommenting the
LibParseOperand.handleOperandDisallowedassignment.
581-581: Function pointer updated: Integrity check reference.The integrity function pointer correctly references
LibOpLessThan.integrityinstead of the previousLibOpLessThanNP.integrity.
693-693: Function pointer updated: Runtime execution reference.The runtime function pointer correctly references
LibOpLessThan.runinstead of the previousLibOpLessThanNP.run.
108-108: ALL_STANDARD_OPS_LENGTH increment is correct
Verified that each of the three function‐pointer arrays (operandHandlerFunctionPointers, integrityFunctionPointers, and opcodeFunctionPointers) contains exactly 32 active entries (excluding commented‐out slots), matching the updatedALL_STANDARD_OPS_LENGTH = 32. No further changes needed.src/lib/op/logic/LibOpLessThan.sol (4)
8-9: Appropriate imports for floating-point operations.The addition of
StackItemandFloat/LibDecimalFloatimports enables proper floating-point less-than comparisons.
11-14: Library renamed and documentation updated.The library name change from
LibOpLessThanNPtoLibOpLessThanaligns with the new floating-point implementation.
22-34: Floating-point comparison implementation looks correct.The implementation properly:
- Loads two
Floatvalues from the stack- Uses
LibDecimalFloat.ltfor accurate floating-point comparison- Stores the boolean result back on the stack
- Maintains the expected stack pointer manipulation
37-47: Reference function correctly implements floating-point logic.The reference function properly:
- Converts
StackIteminputs toFloatvalues- Performs the same floating-point comparison as the runtime function
- Returns the boolean result as a
StackItemarraytest/src/lib/op/logic/LibOpLessThan.t.sol (4)
20-38: Comprehensive integrity testing.The integrity tests properly verify that the less-than operation always requires exactly 2 inputs and produces 1 output, regardless of operand values.
40-48: Effective fuzz testing for runtime correctness.The runtime test uses randomized
StackIteminputs and validates against the reference function, providing robust coverage of the floating-point comparison logic.
52-92: Thorough evaluation test coverage.The tests cover important scenarios including:
- Zero comparisons
- Integer comparisons
- Decimal comparisons (1.1 vs 1.2)
- Negative number comparisons
- Mixed integer/decimal comparisons
95-121: Complete error handling validation.The tests properly validate error conditions for incorrect input/output counts, ensuring the integrity checks work as expected.

🧹 Nitpick (assertive)
Fix inconsistent function naming in test comments.
Several test function names still contain the "NP" suffix from the old implementation (lines 64, 70, 75, 80, 85, 90), which should be removed for consistency.

In test/src/lib/op/logic/LibOpLessThan.t.sol between lines 64 and 91, the test
function names include the outdated "NP" suffix. Rename these functions to
remove the "NP" suffix for consistency with the current naming convention,
ensuring the function names accurately reflect their purpose without the old
suffix.
