2013年7月8日 · The total (a) minus what was shared equals the remainder of the division Applied to the last example, this gives: 5 % 7 = 5 - floor(5 / 7) * 7 = 5 Modular Arithmetic That said, your intuition was that it could be -2 and not 5. Actually, in modular arithmetic, -2 = 5 (mod 7) because it exists k in Z such that 7k - 2 = 5.
modulo - Why does 2 mod 4 = 2? - Stack Overflow
2009年8月30日 · I'm embarrassed to ask such a simple question. My term does not start for two more weeks so I can't ask a professor, and the suspense would kill me. Why does 2 mod 4 = 2?
Mod of power 2 on bitwise operators? - Stack Overflow
How does mod of power of 2 work on only lower order bits of a binary number (1011000111011010)? What is this number mod 2 to power 0, 2 to power 4? What does power of 2 have to do with the modulo
modulo - What's the syntax for mod in java - Stack Overflow
2015年11月17日 · Careful with the terms mod and modular because n (mod m) IS ALWAYS >= 0 but not n % m. n % m is in the range > -m and < m. Although Java has a remainder operator for int and long types, it has no modulus function or operator. I.e., -12 % 10 = -2 whereas -12 mod 10 = 8. If % operator returns a negative value for n % m, then (n % m) + m will give you n mod m. BigInteger provides functions for ...

How does the % operator (modulo, remainder) work?
2024年10月2日 · You can think of the modulus operator as giving you a remainder. count % 6 divides 6 out of count as many times as it can and gives you a remainder from 0 to 5 (These are all the possible remainders because you already divided out 6 as many times as you can). The elements of the array are all printed in the for loop, but every time the remainder is 5 (every 6th element), it outputs a newline ...
How to calculate modulus of large numbers? - Stack Overflow
2010年2月1日 · How to calculate modulus of 5^55 modulus 221 without much use of calculator? I guess there are some simple principles in number theory in cryptography to calculate such things.
python - What does x % 2 ==0 mean? - Stack Overflow
2013年4月21日 · x % 2 gives the remainder after the integer division (when dealing with only integers such as in this case, otherwise a common type) of x/2. The % is called the modulo operator. Of course when the remainder is 0, the number is even. Docs: The % (modulo) operator yields the remainder from the division of the first argument by the second.
