Python | fsum() function

Last Updated : 16 Feb, 2023

fsum() is inbuilt function in Python, used to find sum between some range or an iterable. To use this function we need to import the math library. Syntax :

maths.fsum( iterable )

Parameter :

iterable : Here we pass some value
which is iterable like arrays, list.

Use :

fsum() is used to find the sum
of some range, array , list.

Return Type :

The function return a
floating point number.

Time Complexity: O(n) where n is the size of the list.

Auxiliary Space: O(1)

Code demonstrating fsum() :

Python3

# Python code to demonstrate use  
# of math.fsum() function

# fsum() is found in math library
import math

# range(10)
print(math.fsum(range(10)))

# Integer list
arr = [1, 4, 6]
print(math.fsum(arr))

# Floating point list
arr = [2.5, 2.4, 3.09]
print(math.fsum(arr))

Output :

45.0
11.0
7.99
