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 4.08.0
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 4.08.0
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 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 4.08.0
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 conversion 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 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 4.08.0
val equal : t -> t -> bool
The equal function for int64s.
Since 4.03.0
val min : t -> t -> t
Return the smaller of the two arguments.
Since 4.13.0
val max : t -> t -> t
Return the greater of the two arguments.
Since 4.13.0
