Math libraries are considered an extension of the hardware, providing common mathematical functions not supplied in hardware. Users expect these func­ tions to be as accurate as the basic machine instruc­ tions, whether or not these expe ctations are always justified. Presented in this paper are the performance and accuracy evaluations of eleven transcendental func­ tions found in 64 and 128 bitfloating-poin tf ormats in math libraries on the CRAY Y-MP, the IBM 3090EIVF, the Convex C-240, the Hewlett Packard 90001720 and the IBM Systeml6000. Both architecture and algo­ rithms are shown to impact the results.
