Modulo operator
A modulo is a mathematical operator used in modular arithmetic You can think about modular arithmetic like how time on an analog clock works. In a 12 hr clock, if it’s currently 10, in 3 hours it will be 1, not 13. This is expressed as 10 + 3 mod 12. The modulo operator returns that result. num = (10 + 3) % 12 print(num) Would output 1. People like thinking about this as the remainder, but that’s not really accurate. For example: -1 % 4 would actually equal 3. If you think about a 4-hr clock and go back 1 hour, you end up at 3.

November 22, 2023How come Python performs modulo operation so quickly, even when the dividend and thre divisor are extremely big?
Computers are fast. Modern CPUs can do arithmetic operations in one clock cycle, so a 2GHz CPU can do 2 billion arithmetic operations per second. When dealing with large numbers, Python breaks them down into repeated calculations using smaller numbers, in a similar way to how humans do long division. But even if it needs to do loads of operations, it still feels instant, because CPUs are so fast. More on reddit.com

May 25, 2023Inaccurate results using mod operator in python
This looks like an example of floating point numbers not being accurate, e.g. if you ask what 0.1 * 3 is you don't get 0.3, you get 0.30000000000000004. Not sure if there are ways round it in general, but if you know that you'll only use numbers with few decimal places you can use round() so that 0.30000000000000004 becomes 0.3, or truncate/floor/ceiling.

When I was at school we called it remainder. What is 11 divided by 3? The answer is 3 remainder 2. The modulo operator gives you the remainder part of the division, ignoring the main answer. So 11 % 3 gives 2 And hence N % M always returns an answer between 0 and (M - 1).
