1. sum :: (Foldable t, Num a) => t a -> a

   incipit-base	Incipit.Foldable

   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 *
   

2. sum :: (Generator c, Num (Elem c)) => c -> Elem c

   reducers	Data.Generator.Combinators

   Efficiently sum over the members of any Generator

   reduceWith getSum
   

3. sum :: forall (m :: Type -> Type) a . (Monad m, Num a) => Fold m a a

   streamly-core	Streamly.Data.Fold

   Determine the sum of all elements of a stream of numbers. Returns additive identity (0) when the stream is empty. Note that this is not numerically stable for floating point numbers.

   >>> sum = Fold.cumulative Fold.windowSum
   

   Same as following but numerically stable:

   >>> sum = Fold.foldl' (+) 0
   
   >>> sum = fmap Data.Monoid.getSum $ Fold.foldMap Data.Monoid.Sum
   

4. sum :: forall (m :: Type -> Type) a . (Monad m, Num a) => Fold m a a

   streamly-core	Streamly.Internal.Data.Fold

   Determine the sum of all elements of a stream of numbers. Returns additive identity (0) when the stream is empty. Note that this is not numerically stable for floating point numbers.

   >>> sum = Fold.cumulative Fold.windowSum
   

   Same as following but numerically stable:

   >>> sum = Fold.foldl' (+) 0
   
   >>> sum = fmap Data.Monoid.getSum $ Fold.foldMap Data.Monoid.Sum
   

5. sum :: C a => [a] -> a

   battleship-combinatorics	Combinatorics.Battleship.Count.Counter

   No documentation available.

6. sum :: (Foldable t, Num a) => t a -> a

   calligraphy	Calligraphy.Prelude

   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 *
   

7. sum :: (Foldable t, Num a) => t a -> a

   clash-prelude	Clash.HaskellPrelude

   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 *
   

8. sum :: (C sh, Floating a) => Vector sh a -> a

   comfort-blas	Numeric.BLAS.Vector

   forVector number_ $ \xs -> Vector.sum xs == List.sum (Vector.toList xs)
   

9. sum :: (C sh, Floating a) => T shA sh a -> a

   comfort-blas	Numeric.BLAS.Vector.Slice

   forSliced number_ $ \xs -> VectorSlice.sum xs == List.sum (listFromSlice xs)
   

10. sum :: (Typed a, Num a, Eq a) => Int -> Stream a -> Stream a

    copilot-libraries	Copilot.Library.Statistics

    Summation.
