I got a function with type :: IO [[Double]], and what I want is write this output in a file, how can I do it... I mean, I cannot doit by just using writeFile....
How about.. do double_list_result <- your_function writefile "/file/path/foo" (show double_list_result)
And one more thing: the Glasglow compiler doesn let me compile because I use the function readFloat (declare in the Prelude of Hugs 98), but Hugs lets me, why? How can I solve it?
a solution is myreadfloat string = (read string) :: Float (assuming readFloat is a function String -> Float and not something like Handle -> IO Float) Jay Cox
