Python math.fmod() method “returns the remainder (modulo) of x/y”.
Syntax
math.fmod(x,y)
Parameters
The math.fmod() function takes two arguments: x and y (both positive or negative), which find x%y.
Return Value
After calculating the module of the given two numbers, the fmod() function returns a floating-point number value.
- If x and y are both zero, math.fmod() method returns a ValueError.
- If the second argument means y is zero, it returns a ValueError.
- If any of x or y is not a number, this function returns a TypeError.
Time Complexity: O(1)
Auxiliary Space: O(1)
Example 1: How to Use math.fmod() Method
import math
# When both are positive
x = 12
y = 9
print("Module of ", x, " and ", y, "is: ", math.fmod(x, y))
# When any one of them are negative
x = -16
y = 3
print("Module of ", x, " and ", y, "is: ", math.fmod(x, y))
# When both are negative
x = -65
y = -31
print("Module of ", x, " and ", y, "is: ", math.fmod(x, y))
# When second argument (y) is 0
x = 10
y = 0
print("Module of ", x, " and ", y, "is: ", math.fmod(x, y))
Output
Module of 12 and 9 is: 3.0
Module of -16 and 3 is: -1.0
Module of -65 and -31 is: -3.0
ValueError: math domain errorExample 2: Using math.fmod() method tuples and lists
We can use the same logic in Tuples and Lists by referring to the individual elements in Tuples and logic.
import math
Tuple = (21, 19, -11, -46)
List = [-69, 10, -48, 30]
print("\nTuples: ")
print(math.fmod(Tuple[3], 7))
print(math.fmod(Tuple[1], -7))
print("Lists: ")
print(math.fmod(List[3], 6))
print(math.fmod(List[0], -25))
Output
Tuples:
-4.0
5.0
Lists:
0.0
-19.0
Example 3: ValueError and TypeError
import math
print(math.fmod(0, 0))
print(math.fmod(21, 0))
print(math.fmod('3', 3))
Output
ValueError: math domain error
