Table-driven techniques can be used to test highly accurate implementation of EXP LOG. The largest error observeed in EXP and LOG accurately to within 1/500 unit in the last place are reported in our tests. Methods to verify the tests' reliability are discussed. Results of applying the tests to our own as well as to a number of other implementations of EXP and LOG are presented.
