module BatInt64:sig..end
This module provides operations on the type int64
of signed 64-bit integers. Unlike the built-in int type,
the type int64 is guaranteed to be exactly 64-bit wide on all
platforms. All arithmetic operations over int64 are taken
modulo 264.
Performance notice: values of type int64 occupy more memory
space than values of type int, and arithmetic operations on
int64 are generally slower than those on int. Use int64
only when the application requires exact 64-bit arithmetic.
Any integer literal followed by L is taken to be an int64.
For instance, 1L is Int64.one.
This module extends Stdlib's
Int64
module, go there for documentation on the rest of the functions
and types.

The result is unspecified if y < 0 or y >= 64.val shift_right : int64 -> int -> int64Int64.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 >= 64.val shift_right_logical : int64 -> int -> int64Int64.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.
