sum -package:streaming
The
sum function computes the sum of the numbers of a
structure.
Examples
Basic usage:
>>> sum []
0
>>> sum [42]
42
>>> sum [1..10]
55
>>> sum [4.1, 2.0, 1.7]
7.8
>>> sum [1..]
* Hangs forever *
The
sum function computes the sum of a finite list of numbers.
>>> sum []
0
>>> sum [42]
42
>>> sum [1..10]
55
>>> sum [4.1, 2.0, 1.7]
7.8
>>> sum [1..]
* Hangs forever *
O(n) Compute the sum of the elements.
Examples
>>> import qualified Data.Vector as V
>>> V.sum $ V.fromList [300,20,1]
321
>>> V.sum (V.empty :: V.Vector Int)
0
O(n) Compute the sum of the elements.
Examples
>>> import qualified Data.Vector.Strict as V
>>> V.sum $ V.fromList [300,20,1]
321
>>> V.sum (V.empty :: V.Vector Int)
0
O(n) Compute the sum of the elements.
Examples

>>> VP.sum $ VP.fromList [300,20,1 :: Int]
321
>>> VP.sum (VP.empty :: VP.Vector Int)
0
O(n) Compute the sum of the elements.
Examples
>>> import qualified Data.Vector.Storable as VS
>>> VS.sum $ VS.fromList [300,20,1 :: Int]
321
>>> VS.sum (VS.empty :: VS.Vector Int)
0
O(n) Compute the sum of the elements.
Examples

>>> VU.sum $ VU.fromList [300,20,1 :: Int]
321
>>> VU.sum (VU.empty :: VU.Vector Int)
0
