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