Please see the test updated to use `@key randomness` and` jdk.test.lib.RandomFactory` to get and Random object. > The allowable worst-case error is 2.5 ulp, although at many arguments FDLIBM > has a smaller error. > For a general Math vs StrictMath test with an allowable 2.5 ulp error, > without knowing how accurate FDLIBM is for that function and argument, a > large error of approx. 2X the nominal error should be allowed (in case FDLIBM > errors in one direction and the Math method errors in the other direction). > So far the tests haven't failed with error of 2.5ulp. Would it be better to make it 5ulp? Please let me know. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/20657#discussion_r1746034895
