32 * The tests in ../Math/CubeRootTests.java test properties that should
33 * hold for any cube root implementation, including the FDLIBM-based
34 * one required for StrictMath.cbrt. Therefore, the test cases in
35 * ../Math/CubeRootTests.java are run against both the Math and
36 * StrictMath versions of cube root. The role of this test is to
37 * verify that the FDLIBM cbrt algorithm is being used by running
38 * golden file tests on values that may vary from one conforming cube
39 * root implementation to another.
