754-832: Excellent comprehensive test coverage with robust property-based testing.The test suite is well-structured and covers:
- Unit tests for integer and floating-point inputs
- Property-based tests verifying mathematical invariants:
floor(x).frac() == 0(floor has no fractional part)frac(x).floor() == 0(fractional part's floor is zero)x == floor(x) + frac(x)(decomposition property)-1 < frac(x) < 1(fractional part bounds)This thorough testing approach ensures the mathematical correctness of the implementations and provides confidence in the functionality.

🧹 Nitpick (assertive)
Consider consolidating impl blocks for better code organization.
The frac and floor methods are correctly implemented and follow the established patterns. However, having a separate impl block for these methods creates unnecessary fragmentation.
Consider moving these methods to the main impl block (starting at line 137) to keep all Float methods together:
-impl Float {
- pub fn frac(self) -> Result<Float, FloatError> {
- let Float(a) = self;
- let calldata = DecimalFloat::fracCall { a }.abi_encode();
-
- execute_call(Bytes::from(calldata), |output| {
- let decoded = DecimalFloat::fracCall::abi_decode_returns(output.as_ref())?;
- Ok(Float(decoded))
- })
- }
-
- pub fn floor(self) -> Result<Float, FloatError> {
- let Float(a) = self;
- let calldata = DecimalFloat::floorCall { a }.abi_encode();
-
- execute_call(Bytes::from(calldata), |output| {
- let decoded = DecimalFloat::floorCall::abi_decode_returns(output.as_ref())?;
- Ok(Float(decoded))
- })
- }
-}And add these methods to the main impl block instead.

🤖 Prompt for AI Agents
In crates/float/src/lib.rs between lines 326 and 346, the frac and floor methods
are implemented in a separate impl block, causing fragmentation. To fix this,
move these methods into the main Float impl block that starts around line 137,
consolidating all Float methods into a single impl block for better organization
and maintainability.

this isn't needed and organization will be updated later anyway

@0xgleb Understood! You're right that the core functionality is what matters for this PR. The frac and floor methods are implemented correctly and follow the established patterns. Code organization can indeed be addressed in a future refactoring when you're ready to tackle the broader structural improvements.
