The RemainderOperator does not handle negative numbers the same way as the .net remainder operator.

These test fail.

            Expression expr4 = new Expression("5%-4");
            Assert.AreEqual(1M, expr4.Eval<decimal>());

            Expression expr5 = new Expression("-5%4");
            Assert.AreEqual(-1M, expr5.Eval<decimal>());

            Expression expr6 = new Expression("-5.2%2.0");
            Assert.AreEqual(-1.2M, expr6.Eval<decimal>());
