Python math.fsum() – Sum of Values in Iterable

Python math.fsum()

math.fsum(x) function returns the sum of items in the iterable x.

Syntax

The syntax to call fsum() function is

math.fsum(x)

where

Parameter	Required	Description
x	Yes	An iterable.

Examples

Sum of items in a list using math.fsum() function.

Python Program

import math

x = list([2.4, 5.1, 6.7])
result = math.fsum(x)
print('fsum(x) :', result)

Run

Output

fsum(x) : 14.2

Sum of items in a tuple using math.fsum() function.

Python Program

import math

x = tuple([2.4, 5.1, 6.7])
result = math.fsum(x)
print('fsum(x) :', result)

Run

Output

fsum(x) : 14.2

Sum of items in a range using math.fsum() function.

Python Program

import math

x = range(5)
result = math.fsum(x)
print('fsum(x) :', result)

Run

Output

fsum(x) : 10.0

Return value of fsum() when there is one or more infinity values, and the rest float/integral values, in the iterable.

Python Program

import math

x = [math.inf, 5, 3.2]
result = math.fsum(x)
print('fsum(x) :', result)

Run

Output

fsum(x) : inf

Return value of fsum() when there is at least one nan value in the iterable.

Python Program

import math

x = [math.nan, 5, 3.2]
result = math.fsum(x)
print('fsum(x) :', result)

Run

Output

fsum(x) : nan
