Benchmarking Large Language Models on Floating-Point Error Classification

arXiv:2606.31308v1 Announce Type: new Abstract: This paper investigates the capability of Large Language Models (LLMs) to detect and classify floating-point errors statically in software code. We introduce InterFLOPBench, a benchmark of 90 C kernels with 1 130 test samples designed to evaluate LLMs across six categories of floating-point error: cancellation, comparison, division by zero, overflow, underflow and NaN, compared across 14 LLMs. The evaluation framework treats floating-point error detection as a multi-label classification problem and employs the F1-score metric to measure performan

Why this matters
Why now

As LLMs become more sophisticated and integrated into complex software development, their ability to handle subtle but critical programming errors like floating-point issues becomes a key focus for reliability and safety.

Why it’s important

This research highlights the growing role of AI in automating highly technical and error-prone aspects of software engineering, potentially enhancing code quality and reducing development costs across various industries.

What changes

The explicit benchmarking of LLMs on specific and critical code error types demonstrates a measurable advancement in AI's capacity for code analysis and bug detection, moving beyond general code generation.
