module BatInt32:sig..end
This module provides operations on the type int32
of signed 32-bit integers. Unlike the built-in int type,
the type int32 is guaranteed to be exactly 32-bit wide on all
platforms. All arithmetic operations over int32 are taken
modulo 232.
Any integer literal followed by l is taken to be an int32.
For instance, 1l is Int32.one.
Performance notice: values of type int32 occupy more memory
space than values of type int, and arithmetic operations on
int32 are generally slower than those on int. Use int32
only when the application requires exact 32-bit arithmetic.
This module extends Stdlib's
Int32
module, go there for documentation on the rest of the functions
and types.

The result is unspecified if y < 0 or y >= 32.val shift_right : int32 -> int -> int32Int32.shift_right x y shifts x to the right by y bits.
This is an arithmetic shift: the sign bit of x is replicated
and inserted in the vacated bits.
The result is unspecified if y < 0 or y >= 32.val shift_right_logical : int32 -> int -> int32Int32.shift_right_logical x y shifts x to the right by y bits.
This is a logical shift: zeroes are inserted in the vacated bits
regardless of the sign of x.
