[Haskell-cafe] cumulative sum

[Matthias Fischmann]

> try
> scanl (+) 0
> for the cumulative sum

and it is probably worth pointing out once more that (as i have
learned only recently :-) Hoogle can help you even quicker than this
list with questions like these: scanl is the fifth answer if you ask
for a -> [a] -> [a].

also, the url is easy to remember: http://www.haskell.org/hoogle/
