You should have a look at the Read class. A member a of the Read class has a function read :: String -> a. so, for example, you can say: (read "5.0") :: Double to read this as a double. You could also read it as an integer or something. If you have a list of strings that you want to convert to a list of integers, you could do: map (\x -> (read x)::Double) [list of strings] Hope that helps. - Hal -- Hal Daume III "Computer science is no more about computers | hdaume@isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume On Thu, 7 Feb 2002, DK wrote:

Hello. First of all I am a beginner in Haskell, and I must confess I do not yet fully understand it. I need to write a program in Haskell, though, and I am having some difficulties...

What I would like to ask, is how can I take a string from a list, and manipulate it, in order to convert it to an integer. Any help would be very appreciated.

Thank you very much, Dimitris
