Hi,
I try to understand, how Parsec works. In Pos.hs I found
these definition of SourcePos:
data SourcePos = SourcePos SourceName !Line !Column
deriving (Eq,Ord)
My poor haskell knowledge says me, that Line and Column is
always strict. So, what does the following function?
forcePos :: SourcePos -> SourcePos
forcePos pos@(SourcePos name line column)
= seq line (seq column (pos))
thanks for an enlightenment,
Christoph Bauer

let () = let rec f a w i j = Printf.printf "%.20f\r" a; let a1 = a *. i /. j in
if w then f a1 false (i +. 2.0) j else f a1 true i (j +. 2.0) in f 2.0 false
2.0 1.0
