At 10:40 in the video please note for rint() function: Math rint(7.5) will return 8.0 and Math.rint(8.5) will also return 8.0 Here, in both cases, the value after the decimal is equal to 5. However, for 7.5 - the method is rounding up for 8.5 - the method is rounding down. It is because, in the case of .5, the method rounds to nearest even value. Hence, in both cases, the method rounds to 8.0. Happy Learning
