       64-bit integers.

       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 2^{64

       Performance notice: values of type int64 occupy more memory space than values of type int , and arithmetic operations on int64  are  gener-
       ally slower than those on int .  Use int64 only when the application requires exact 64-bit arithmetic.

       val zero : int64

       The 64-bit integer 0.

       val one : int64

       The 64-bit integer 1.

       val minus_one : int64

       The 64-bit integer -1.

       val neg : int64 -> int64

       Unary negation.

       val add : int64 -> int64 -> int64

       Addition.

       val sub : int64 -> int64 -> int64

       Subtraction.

       val mul : int64 -> int64 -> int64

       Multiplication.

       val div : int64 -> int64 -> int64

       Integer  division.  Raise Division_by_zero if the second argument is zero.  This division rounds the real quotient of its arguments towards
       zero, as specified for Pervasives.(/) .

       val rem : int64 -> int64 -> int64

       Integer remainder.  If y 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 -> int64

       Successor.  Int64.succ x is Int64.add x Int64.one .

       val pred : int64 -> int64

       Predecessor.  Int64.pred x is Int64.sub x Int64.one .

       val abs : int64 -> int64

       Return the absolute value of its argument.

       val max_int : int64

       The greatest representable 64-bit integer, 2^{63 - 1.

       val min_int : int64

       The smallest representable 64-bit integer, -2^{63.

       val logand : int64 -> int64 -> int64

       Bitwise logical and.

       val logor : int64 -> int64 -> int64

       Bitwise logical or.

       val logxor : int64 -> int64 -> int64

       Bitwise logical exclusive or.

       val lognot : int64 -> int64

       Bitwise logical negation

       val shift_left : int64 -> int -> int64

       Int64.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 -> int64

       Int64.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 -> int64

       Int64.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 -> int64

       Convert the given integer (type int ) to a 64-bit integer (type int64 ).

       val to_int : int64 -> int

       Convert  the  given 64-bit integer (type int64 ) to an integer (type int ).  On 64-bit platforms, the 64-bit integer is taken modulo 2^{63,
       i.e. the high-order bit is lost during the conversion.  On 32-bit platforms, the 64-bit integer is taken modulo 2^{31, i.e. the top 33 bits
       are lost during the conversion.

       val of_float : float -> int64

       Convert  the  given floating-point number to a 64-bit integer, discarding the fractional part (truncate towards 0).  The result of the con-
       version is undefined if, after truncation, the number is outside the range [ Int64.min_int , Int64.max_int ].

       val to_float : int64 -> float

       Convert the given 64-bit integer to a floating-point number.

       val of_int32 : int32 -> int64

       Convert the given 32-bit integer (type int32 ) to a 64-bit integer (type int64 ).

       val to_int32 : int64 -> int32

       Convert the given 64-bit integer (type int64 ) to a 32-bit integer (type int32 ). The 64-bit integer is taken modulo 2^{32, i.e. the top 32
       bits are lost during the conversion.

       val of_nativeint : nativeint -> int64

       Convert the given native integer (type nativeint ) to a 64-bit integer (type int64 ).

       val to_nativeint : int64 -> nativeint

       Convert  the  given  64-bit  integer (type int64 ) to a native integer.  On 32-bit platforms, the 64-bit integer is taken modulo 2^{32.  On
       64-bit platforms, the conversion is exact.

       val of_string : string -> int64

       Convert the given string to a 64-bit integer.  The string is read in decimal (by default) or in hexadecimal, octal or binary if the  string
       begins with 0x , 0o or 0b respectively.  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 -> string

       Return the string representation of its argument, in decimal.

       val bits_of_float : float -> int64

       Return the internal representation of the given float according to the IEEE 754 floating-point ``double format'' bit layout.  Bit 63 of the
       result represents the sign of the float; bits 62 to 52 represent the (biased) exponent; bits 51 to 0 represent the mantissa.

       val float_of_bits : int64 -> float

       Return  the  floating-point number whose internal representation, according to the IEEE 754 floating-point ``double format'' bit layout, is
       the given int64 .

       type t = int64

       An alias for the type of 64-bit integers.

       val compare : t -> t -> int

       The comparison function for 64-bit integers, with the same specification as Pervasives.compare .  Along with the type  t  ,  this  function
       compare allows the module Int64 to be passed as argument to the functors Set.Make and Map.Make .
