Abstract
This paper explores the principles and numerics behind the use of identities to test the accuracy of elementary function software. The success of this approach depends critically on proper matching of identity and test interval with the purpose of the test, and on careful implementation based on an understanding of computer arithmetic systems and inherent accuracy limitations for computational software.
