![]() ![]() Further ReadingĮxplore modular arithmetic and modulo operations further including a mod b for negative numbers. Similarly, 5 mod 10 = 5 since 10 divides into 5 zero times with 5 left over as the remainder.įor positive numbers, whenever the divisor (modulus) is greater than the dividend, the remainder is the same as the dividend. Example: 1 mod 2ġ mod 2 is a situation where the divisor, 2, is larger than the dividend, 1, so the remainder you get is equal to the dividend, 1.įor 1 divided by 2, 2 goes into 1 zero times with a remainder of 1. In some calculators and computer programming languages a % b is the same as a mod b is the same as a modulo b where % or mod are used as the modulo operators. 226 mod 4 = 2, so no, 226 is not a multiple of 4. Is 226 a multiple of 4? Divide 226 by 4, so 226 / 4 = 56 with a remainder of 2. In terms of mod, 496 mod 4 = 0, so yes, 496 is a multiple of 4. You would divide 496 by 4, so 496 / 4 = 124 with no remainder. For example you would have to calculate "is 496 a multiple of 4?". If you did not use the mod operator you would have to do the math in your code. Now convert 1 to 0 and 0 to 1, so number is 1110 1011 and add 1 in one’s complement to get. For instance, to convert decimal to 2’s complement, we have a number (20)10 which is equal to (0001 0100)2. If x mod 4 = 0 then x is a multiple of 4 To get 2’s complement of a binary system, just transpose the certain number and add one to the LSB (Least Significant Bit) of given results. ![]() The logic for this part of your program would be: If the result is 0 the number is a multiple of 4 otherwise the number is not a multiple of 4. So you would create the logic to take an input and use the mod 4 operation on it. If a number is a multiple of 4, when you divide it by 4 the remainder will be 0. You can use the modulo calculation to accomplish this. You need to write a piece of software that tells a user whether a number they input is a multiple of 4. ![]() If you needed to find 27 mod 6, divide 27 by 6. To do this by hand just divide two numbers and note the remainder. The modulo operation finds the remainder of a divided by b. The modulo operation finds the remainder, so if you were dividing a by b and there was a remainder of n, you would say a mod b = n. Calculate a mod b which, for positive numbers, is the remainder of a divided by b in a division problem. ![]()
