Data.Int

Description

Signed integer types

Synopsis

Signed integer types

data Int Source #

A fixed-precision integer type with at least the range [-2^29 .. 2^29-1]. The exact range for a given implementation can be determined by using minBound and maxBound from the Bounded class.

Notes

  • All arithmetic is performed modulo 2^n, where n is the number of bits in the type.
  • For coercing between any two integer types, use fromIntegral, which is specialized for all the common cases so should be fast enough. Coercing word types (see Data.Word) to and from integer types preserves representation, not sign.
  • The rules that hold for Enum instances over a bounded type such as Int (see the section of the Haskell report dealing with arithmetic sequences) also hold for the Enum instances over the various Int types defined here.
  • Right and left shifts by amounts greater than or equal to the width of the type result in either zero or -1, depending on the sign of the value being shifted. This is contrary to the behaviour in C, which is undefined; a common interpretation is to truncate the shift count to the width of the type, for example 1 << 32 == 1 in some C implementations.
