Yeah, "fromIntegral/Int->Float" fromIntegral = int2Float "truncate/Float->Int" truncate = float2Int "truncate/Double->Int" truncate = double2Int with appropriate no-op fromIntegrals for the 32 and 64 variants. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
