# Modulo Operator python-modulus in python

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 :

numx % numy

output:

For example:

11 % 2

output:

1

If any case the divisor result is equal to zero then output show ZeroDivisionError:

11 % 0

output:

ZeroDivisionError: modulo by zero.

The modulo operator also work on floating numbers as arguments:**for example:**

4.8 % 1.2

0.0

Remember % character represents the interpolation operator.(formatting strings)**Examples**

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:**

numx = 15

if (numx % 5) == 0:

print(num, "is even no.")

else:

print(num, "is odd no.")

output:

15 is even no.

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:**

def is PrimeNumber(numb):

if numb < 1:

return False

for i in range(2, numb):

if (numb % i) == 0:

return False

else:

return True

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 –

-3 % 7 = ( -1*7 + 4 ) % 7 = 4

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.

11 % 0

output:

ZeroDivisionError: modulo by zero.

res1 = -35% 5

res2 = - 17 % 5

print(result1)

print(result2)

**Some FAQ about Modulo Operator python:**

### 1.How does a modulo operator work?

The **modulus operator** is a path or way to determine the remainder of a division in any mathematics problem. The **modulo** operations return the whole numbers instead of returning the result of the division.

#### 2.What is the use of modulo operator?

The **modulo** operations return the whole numbers instead of returning the result of the division. Modulo is indicated with a percent sign in most of place. For **example**, “10 mod 5” or “10%5” returns 0, because 5 divide into 10 perfectly, without a remainder.

3.How do you find modulo?

**How to calculate the**

**modulo**– an example- choosing the starting numbers
- Then Choose the divisor.
- Divide one number by divisor
- and multiply the divisor by the quotient.
- Subtract number
- Finally we got modulo

4.What is the symbol of modulus operator?

mod, or indicated by the symbol %
