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