    Description

      Take the following testcase

      Assert.assertEquals(neginf, inf* neginf, Double.MIN_VALUE);  // <--Passes ordinary double
      Assert.assertEquals(new Complex(neginf, 0), new Complex(inf, 0).multiply(new Complex(neginf, 0)));// <-- Fail only real parts no imaginary parts 
      

      The outcome of multiply is Complex.INF if one part is infinity.
      why not simply compute the multiplication and thats is?
