hi there.... System.out.println(Math.floor(-2.1)); what do you think the answer is? -3.0 that's what. i thought it rounded towards zero...i guess it does with positive numbers, but the point is that .floor gets the lowest whole number... so therefore it must be -3.0 ... silly little things like that must be watched for on the exam eh.
