Worked on the sharkdp/numbat repository to enhance the reliability of numeric operations by addressing exponentiation edge cases in Rust. Focused on backend development, the work introduced explicit error handling for scenarios where zero is raised to a negative power, mapping these to user-facing division by zero errors. This involved updating the power function and virtual machine logic to catch and remap errors, ensuring consistent error semantics. Comprehensive tests were added to validate these edge cases, improving both error reporting and code robustness. The changes strengthened the reliability of core math operations and clarified error messages for end users and developers.
