Description
Signed integer types
Signed integer types
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
nis 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
Enuminstances over a bounded type such asInt(see the section of the Haskell report dealing with arithmetic sequences) also hold for theEnuminstances over the variousInttypes 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 == 1in some C implementations.
