    Description

      There are no unit tests for FastMath.signum(double) as yet.

      Here is one that should work, but fails:

      @Test
      public void testSignum() {
          Assert.assertTrue(Double.valueOf(FastMath.signum(+0.0)).equals(Double.valueOf(Math.signum(+0.0)))); // OK
          Assert.assertTrue(Double.valueOf(FastMath.signum(-0.0)).equals(Double.valueOf(Math.signum(-0.0)))); // FAILS
      }
