> Math.min always returns "-0.0" when comparing doubles and floats of the same value. 
This is a regression since revision 788021 "Minor optimization suggested by Ian on HARMONY-6242
(Math.max(double, double) gives wrong answer when Math.max(-0.0d, 0.0d))".
> testcase:
> assertEquals(1.0, Math.min( 1.0 , 1.0 ));  // gives expected:<1.0> but was:<-0.0>
> assertEquals(1.0f, Math.min( 1.0f , 1.0f ));  // again, gives expected:<1.0> but
was:<-0.0>
> Math.max doesn't fail in this way.
