31/**
32 * The tests in ../Math/HyperbolicTests.java test properties that
33 * should hold for any implementation of the hyperbolic functions
34 * sinh, cos, and tanh, including the FDLIBM-based ones required by
35 * the StrictMath class.  Therefore, the test cases in
36 * ../Math/HyperbolicTests.java are run against both the Math and
37 * StrictMath versions of the hyperbolic methods.  The role of this
38 * test is to verify that the FDLIBM algorithms are being used by
39 * running golden file tests on values that may vary from one
40 * conforming implementation of the hyperbolics to another.
