Stdlib.Int64(3) OCaml library Stdlib.Int64(3) NAME Stdlib.Int64 - no description Module Module Stdlib.Int64 Documentation Module Int64 : (module Stdlib__Int64) 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. Raises Division_by_zero if the second argument is zero. This division rounds the real quotient of its arguments towards zero, as specified for (/) . val unsigned_div : int64 -> int64 -> int64 Same as Int64.div , except that arguments and result are interpreted as unsigned 64-bit integers. Since 4.08 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 unsigned_rem : int64 -> int64 -> int64 Same as Int64.rem , except that arguments and result are interpreted as unsigned 64-bit integers. Since 4.08 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 abs x is the absolute value of x . On min_int this is min_int itself and thus remains negative. 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 unsigned_to_int : int64 -> int option Same as Int64.to_int , but interprets the argument as an unsigned integer. Returns None if the unsigned value of the argument cannot fit into an int . Since 4.08 val of_float : float -> int64 Convert the given floating-point number to a 64-bit integer, discarding the fractional part (truncate towards 0). If the truncated floating-point number is outside the range [ Int64.min_int , Int64.max_int ], no exception is raised, and an unspecified, platform-dependent integer is returned. 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 if the string begins with 0u ) or in hexadecimal, octal or binary if the string begins with 0x , 0o or 0b respectively. The 0u prefix reads the input as an unsigned integer in the range [0, 2*Int64.max_int+1] . If the input exceeds Int64.max_int it is converted to the signed integer Int64.min_int + input - Int64.max_int - 1 . The _ (underscore) character can appear anywhere in the string and is ignored. Raises Failure 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 of_string_opt : string -> int64 option Same as of_string , but return None instead of raising. Since 4.05 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 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 . val unsigned_compare : t -> t -> int Same as Int64.compare , except that arguments are interpreted as unsigned 64-bit integers. Since 4.08 val equal : t -> t -> bool The equal function for int64s. Since 4.03 val min : t -> t -> t Return the smaller of the two arguments. Since 4.13 val max : t -> t -> t Return the greater of the two arguments. Since 4.13 val seeded_hash : int -> t -> int A seeded hash function for 64-bit ints, with the same output value as Hashtbl.seeded_hash . This function allows this module to be passed as argument to the functor Hashtbl.MakeSeeded . Since 5.1 val hash : t -> int An unseeded hash function for 64-bit ints, with the same output value as Hashtbl.hash . This function allows this module to be passed as argument to the functor Hashtbl.Make . Since 5.1 OCamldoc 2024-02-29 Stdlib.Int64(3)
