Analysing Computer Arithmetic to Improve Software Reliability

Grant number: DP140102194 | Funding period: 2014 - 2018



Most computer programs deal with integers. Automated tools designed to verify the correct behaviour of software usually assume the software deals with idealised mathematical integers, since this simplifies reasoning significantly. In reality, most programs work with integer number representations that approximate the ideal. This compromises the soundness of many verification tools. This project will design sound reasoning tools that are aware of the true nature of computer integer arithmetic.
