Short answer: Yes. Long answer: it depends on the order. If x is negative and y is positive, then x-y&lt;0; y-x&gt;0 (this second one is only correct if |y|&lt;&gt;|x|). And if |y|=|x| then y-x=0 (this is the one you're looking for, where x and y are equal, but y is positive and x is negative). Finally, if you know if |y|=|x| or |y|&lt;&gt;|x| then y-x&gt;=0
