Project log

Marc Frincu
added an update
We are currently analyzing several libraries. The candidate list is: newlib 2.4, cr-libm 1.0 beta 5 (now part of MetaLibm), libmcr 0.9, openlibm, and mpfr 3.1.4. We also plan to test versions of Maple and Mathematica. The idea is to test the behavior (ULP, worst case execution time) for single functions as well as known identities.
