Hi.

Can someone tell me if there are any primitives, that used to detect machine type overflows, in ghc haskell ? I perfectly understand, that I can build something based on preconditioning of variables, but this will kill any performance, if needed.
There's http://hackage.haskell.org/package/safeint/ It's not implemented quite as efficiently as it theoretically could be, but it might do more or less what you want. Cheers, Andres -- Andres Löh, Haskell Consultant Well-Typed LLP, http://www.well-typed.com
