The modulo operator, represented by the symbol %, is used to find the remainder of a division operation between two numbers.
How It Works:
- When you divide one number by another, the modulo operator gives you the remainder of that division.
- For example, in the expression
a % b,ais divided byb, and the result is the remainder.
Example:
result = 10 % 3 # result will be 1
In this case:
- 10 divided by 3 equals 3 with a remainder of 1, so
10 % 3equals 1.
Common Uses:
-
Checking Even or Odd:
- A number is even if
number % 2 == 0. - A number is odd if
number % 2 != 0.
- A number is even if
-
Cycling Through Values:
- You can use it to repeat actions every
ntimes, e.g.,if i % n == 0.
- You can use it to repeat actions every
-
Limiting Values:
- To keep a number within a certain range, e.g.,
value % max_value.
- To keep a number within a certain range, e.g.,
Important Note:
- The divisor (the second number) cannot be zero, as this will result in an
ArithmeticException.
