Python | fmod() function

fmod() function is one of the Standard math library function in Python, which is used to calculate the Module of the specified given arguments.

Syntax: math.fmod( x, y )

Parameters:
x any valid number (positive or negative).
y any valid number(positive or negative).

Returns: Return a floating point number value after calculating module of given parameters x and y.

# Python3 program to demonstrate fmod() function
  
import math
  
# Tuple Declaration
Tup = (15, 22, -2, -40 )
  
# List Declaration
Lis = [-89, 38, -39, 16] 
  
# modulus of +ve integer number
print(math.fmod(4, 5))
print(math.fmod(43.50, 4.5))
  
# modulus of -ve integer number
print(math.fmod(-17, 5))
print('%.2f' %math.fmod(-10, 4.78))
  
# modulus of tuple item
print("\nModulus of tuple items:")
print(math.fmod(Tup[2], 5))
print(math.fmod(Tup[2], -6))
  
# modulus of list item
print("\nModulus of list items:")
print(math.fmod(Lis[3], 4))
print(math.fmod(Lis[0], -15))

                        filter_none








Output:


4.0
3.0
-2.0
-0.44

Modulus of tuple items:
-2.0
-2.0

Modulus of list items:
0.0
-14.0



 

Example #2: ValueError and TypeError


    

  • If both the x and y arguments are Zero, fmod() function will return the output as ValueError.
    • 

  • If y argument (second argument) is Zero, fmod() function will return the output as ValueError.
    • 

  • If the x value or y value is not a number, fmod() function will return TypeError.

# Python3 program to demonstrate  


# errors in fmod() function 


  


import math 


  


# will give ValueError 


print(math.fmod(0, 0)) 


print(math.fmod(2, 0)) 


  


# it will give TypeError 


print(math.fmod('2', 3))
