Yes, thanks :) It turns out that Mono's Decimal.GetHashCode
is buggy:

using System;

class Test
{
	static void Main ()
	{
		decimal a = 0.5m;
		decimal b = Math.Round(10.5m - 10, 3);
		Console.WriteLine (a == b);
		Console.WriteLine (a.GetHashCode() == b.GetHashCode());
	}
}

The output should be "true, true", but it's "true, false".
