Because 10,000,000 is too large for a Int, it is always in type of Integer or some higher level data type. ------------------ L.Guo 2007-08-13 ------------------------------------------------------------- From: Alexis Hazell At: 2007-08-13 22:46:46 Subject: Re: [Haskell-cafe] A few questions on primes generating.

2) We have this type definition : pureSieve :: Int -> Int Why there is no error (type mismatch) of this call in func main : pureSieve 10000000
The Haskell Report says that an Int covers at least the range [- 2^29, 2^29 - 1], which that number is well within . . . . why do you think it should report a type error?
