module Int64:64-bit integers.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.
val zero : int64val one : int64val minus_one : int64val neg : int64 -> int64val add : int64 -> int64 -> int64val sub : int64 -> int64 -> int64val mul : int64 -> int64 -> int64val div : int64 -> int64 -> int64Division_by_zero if the second
argument is zero. This division rounds the real quotient of
its arguments towards zero, as specified for (/).val rem : int64 -> int64 -> int64y is not zero, the result
of Int64.rem x y satisfies the following property:
x = Int64.add (Int64.mul (Int64.div x y) y) (Int64.rem x y).
If y = 0, Int64.rem x y raises Division_by_zero.val succ : int64 -> int64Int64.succ x is Int64.add x Int64.one.val pred : int64 -> int64Int64.pred x is Int64.sub x Int64.one.val abs : int64 -> int64val max_int : int64val min_int : int64val logand : int64 -> int64 -> int64val logor : int64 -> int64 -> int64val logxor : int64 -> int64 -> int64val lognot : int64 -> int64val shift_left : int64 -> int -> int64Int64.shift_left x y shifts x to the left by y bits.
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.
The result is unspecified if y < 0 or y >= 64.val of_int : int -> int64int) to a 64-bit integer
(type int64).val to_int : int64 -> intint64) to an
integer (type int). On 64-bit platforms, the 64-bit integer
is taken modulo 263, i.e. the high-order bit is lost
during the conversion. On 32-bit platforms, the 64-bit integer

Raise Failure "int_of_string" if the given string is not
a valid representation of an integer, or if the integer represented
exceeds the range of integers representable in type int64.val to_string : int64 -> stringval bits_of_float : float -> int64val float_of_bits : int64 -> floatint64.typet =int64
