Hello,
Anybody know why in the following program 2147483648::Word32
is printed as '0'?
If I use 2147483647 (2^31-1) it prints correctly.
Using 1::Word32 shift 31 gives the expected value
and maxBound::Word32 gives 2^32 as expected, so it would
seem there is something wrong in the scanner/parser.
Tested using ghc-3.00 on Linux.
Any ideas how to fix this?
Thanks,
Hennus Bergman

module Main (main) where
import Word
import Bits
main = do putStr ("This should be: " ++ show word31 ++ " == 2147483648?\n")
word31 :: Word32
word31 = (2147483648::Word32) -- This gives the value '0'
--word31 = (1::Word32) shift 31 -- This gives the expected value
maxword32 :: Word32
maxword32 = (maxBound::Word32) -- The only? way to get 2^32 directly for
Word32
