Description

This talk will discuss the methods used in constructing the recent improvement in complex divide in libgcc where the gross error rate dropped from more than 1 per 100 tests to less than 1 per 10 million tests. The change in accuracy is platform independent while the modest performance loss varies with platform. We also discuss flaws and likely areas for addressing reducing remaining small errors.
