Module Nativeint
: (module Stdlib__Nativeint)
val zero : nativeint
The native integer 0.
val one : nativeint
The native integer 1.
val minus_one : nativeint
The native integer -1.
val neg : nativeint -> nativeint
Unary negation.
val add : nativeint -> nativeint -> nativeint
Addition.
val sub : nativeint -> nativeint -> nativeint
Subtraction.
val mul : nativeint -> nativeint -> nativeint
Multiplication.
val div : nativeint -> nativeint -> nativeint
Integer division. This division rounds the real quotient of its arguments towards zero, as specified for
(/) .
Raises Division_by_zero if the second argument is zero.
val unsigned_div : nativeint -> nativeint -> nativeint
Same as Nativeint.div , except that arguments and result are interpreted as unsigned native integers.
Since 4.08.0
val rem : nativeint -> nativeint -> nativeint
Integer remainder. If y is not zero, the result of Nativeint.rem x y satisfies the following properties:
Nativeint.zero <= Nativeint.rem x y < Nativeint.abs y and x = Nativeint.add (Nativeint.mul (Nativeint.div
x y) y)
(Nativeint.rem x y) . If y = 0 , Nativeint.rem x y raises Division_by_zero .
val unsigned_rem : nativeint -> nativeint -> nativeint
Same as Nativeint.rem , except that arguments and result are interpreted as unsigned native integers.
Since 4.08.0
val succ : nativeint -> nativeint
Successor. Nativeint.succ x is Nativeint.add x Nativeint.one .
val pred : nativeint -> nativeint
Predecessor. Nativeint.pred x is Nativeint.sub x Nativeint.one .
val abs : nativeint -> nativeint
Return the absolute value of its argument.
val size : int
The size in bits of a native integer. This is equal to 32 on a 32-bit platform and to 64 on a 64-bit
platform.
val max_int : nativeint
The greatest representable native integer, either 2^31 - 1 on a 32-bit platform, or 2^63 - 1 on a 64-bit
platform.
val min_int : nativeint
The smallest representable native integer, either -2^31 on a 32-bit platform, or -2^63 on a 64-bit
platform.
val logand : nativeint -> nativeint -> nativeint
Bitwise logical and.
val logor : nativeint -> nativeint -> nativeint
Bitwise logical or.
val logxor : nativeint -> nativeint -> nativeint
Bitwise logical exclusive or.
val lognot : nativeint -> nativeint
Bitwise logical negation.
val shift_left : nativeint -> int -> nativeint
Nativeint.shift_left x y shifts x to the left by y bits. The result is unspecified if y < 0 or y >=
bitsize , where bitsize is 32 on a 32-bit platform and 64 on a 64-bit platform.
val shift_right : nativeint -> int -> nativeint
Nativeint.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 >= bitsize .
val shift_right_logical : nativeint -> int -> nativeint
Nativeint.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 >=
bitsize .
val of_int : int -> nativeint
Convert the given integer (type int ) to a native integer (type nativeint ).
val to_int : nativeint -> int
Convert the given native integer (type nativeint ) to an integer (type int ). The high-order bit is lost
during the conversion.
val unsigned_to_int : nativeint -> int option
Same as Nativeint.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 -> nativeint
Convert the given floating-point number to a native integer, discarding the fractional part (truncate
towards 0). The result of the conversion is undefined if, after truncation, the number is outside the
range [ Nativeint.min_int , Nativeint.max_int ].
val to_float : nativeint -> float
Convert the given native integer to a floating-point number.
val of_int32 : int32 -> nativeint
Convert the given 32-bit integer (type int32 ) to a native integer.
val to_int32 : nativeint -> int32
Convert the given native integer to a 32-bit integer (type int32 ). On 64-bit platforms, the 64-bit
native integer is taken modulo 2^32, i.e. the top 32 bits are lost. On 32-bit platforms, the conversion
is exact.
val of_string : string -> nativeint
Convert the given string to a native 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*Nativeint.max_int+1] . If the
input exceeds Nativeint.max_int it is converted to the signed integer Int64.min_int + input -
Nativeint.max_int - 1 .
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 nativeint .
val of_string_opt : string -> nativeint option
Same as of_string , but return None instead of raising.
Since 4.05
val to_string : nativeint -> string
Return the string representation of its argument, in decimal.
type t = nativeint
An alias for the type of native integers.
val compare : t -> t -> int
The comparison function for native integers, with the same specification as compare . Along with the
type t , this function compare allows the module Nativeint to be passed as argument to the functors
Set.Make and Map.Make .
val unsigned_compare : t -> t -> int
Same as Nativeint.compare , except that arguments are interpreted as unsigned native integers.
Since 4.08.0
val equal : t -> t -> bool
The equal function for native ints.
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
