The float literal 1e-100000000000000000000000000000000000000000000 in GHC evaluates to 1.0, and 1e-999999999999999999999999999999999999999999999 evaluates to 10.0. Is it a bug, or a documented overflow behavior?
Sounds like a bug to me. I wasn't able to test your example in GHCi because it started consuming all my memory. In GHCi 6.8.2 I got: Prelude> let x = 1e-1000000 *** Exception: stack overflow I tried compiling the following program with "ghc -O --make", and it again started consuming all memory: x = 1e-100000000 :: Double main = print x
What it the correct place to submit bug reports concerning GHC?
