/**

 * The tests in ../Math/HyperbolicTests.java test properties that

 * should hold for any implementation of the hyperbolic functions

 * sinh, cos, and tanh, including the FDLIBM-based ones required by

 * the StrictMath class.  Therefore, the test cases in

 * ../Math/HyperbolicTests.java are run against both the Math and

 * StrictMath versions of the hyperbolic methods.  The role of this

 * test is to verify that the FDLIBM algorithms are being used by

 * running golden file tests on values that may vary from one

 * conforming implementation of the hyperbolics to another.
