modulo operator in python 3.9
Welcome everyone, Today we will see Modulo Operator python,Modulo Operator python for negative number,How does a modulo operator work?,What is the use of modulo operator?,How do you find modulo?,What is the symbol of modulus operator?
so let’s start:
|Modulo Operator python|
Modulo operator is show by the percent sign (%).
The syntax for Modulo Operator python is :
If any case the divisor result is equal to zero then output show ZeroDivisionError:
The modulo operator also work on floating numbers as arguments:
Remember % character represents the interpolation operator.(formatting strings)
modulo operator is used for different purpose like One of the most common use is to check whether a number is even or odd.
If a given number divided by 2 and has no remainder, then this number is even number. Otherwise it is odd.
EXAMPLE 01) Check for even or odd number:
If you run the code above, 15 % 5 leaves a remainder of 0 and the code inside the else statement is executed:
15 is even no.
EXAMPLE 02) Check for prime number:
In this example first, we have to checking if the number, num is a positive number or negative(it’s required positive number). Next step is checking whether the number is divisible by another number in the range from 2 to number without any reminder. If none of the conditions are satisfy, the result is prime number.
Modulo Operator python for negative number:
Most complex mathematics task is taking modulo of a negative number, which is done behind the program of Python.
(x+y)mod z = [(x mod z)+(y mod z)]mod z
To apply this math to given statement as –
This was done so that the (-1*7)%7 will give the answer as 4
Let’s see more examples for better understanding.
Example #1 :
By using this mathematics, we can see able to perform and understand the negative modulo.
