if ($number % 6 != 0) { $number += 6 – ($number % 6); } The modulus operator gives the remainder of the division, so $number % 6 is the amount left over when dividing by 6. This will be faster than doing a loop and continually rechecking. If decreasing is acceptable then this is … Read more
(This explanation is only for positive numbers since it depends on the language otherwise) Definition The Modulus is the remainder of the euclidean division of one number by another. % is called the modulo operation. For instance, 9 divided by 4 equals 2 but it remains 1. Here, 9 / 4 = 2 and 9 … Read more
CMTimeGetSeconds() returns a floating point number (Float64 aka Double). In Swift 2 you could compute the remainder of a floating point division as let rem = 2.5 % 1.1 print(rem) // 0.3 In Swift 3 this is done with let rem = 2.5.truncatingRemainder(dividingBy: 1.1) print(rem) // 0.3 Applied to your code: let totalSeconds = CMTimeGetSeconds(self) … Read more
