Module Janestreet_shims_internal.Nativeint_u

The native integer 0.

The native integer 1.

The native integer -1.

Unary negation.

Addition.

Subtraction.

Multiplication.

Integer division. This division rounds the real quotient of its arguments towards zero, as specified for Stdlib.(/).

• raises Division_by_zero

  if the second argument is zero.

Same as div, except that arguments and result are interpreted as unsigned native integers.

• since 4.08

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.

Same as rem, except that arguments and result are interpreted as unsigned native integers.

• since 4.08

Successor. Nativeint.succ x is Nativeint.add x Nativeint.one.

Predecessor. Nativeint.pred x is Nativeint.sub x Nativeint.one.

abs x is the absolute value of x. On min_int this is min_int itself and thus remains negative.

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.

The greatest representable native integer, either 2³¹ - 1 on a 32-bit platform, or 2⁶³ - 1 on a 64-bit platform.

The smallest representable native integer, either -2³¹ on a 32-bit platform, or -2⁶³ on a 64-bit platform.

Bitwise logical and.

Bitwise logical or.

Bitwise logical exclusive or.

Bitwise logical negation.

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.

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.

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.

Convert the given integer (type int) to a native integer (type nativeint).

Convert the given native integer (type nativeint) to an integer (type int). The high-order bit is lost during the conversion.

Same as 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

Convert the given floating-point number to a native integer, discarding the fractional part (truncate towards 0). If the truncated floating-point number is outside the range [Nativeint.min_int, Nativeint.max_int], no exception is raised, and an unspecified, platform-dependent integer is returned.

Convert the given native integer to a floating-point number.

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

Convert the given native integer to a 32-bit integer (type int32). On 64-bit platforms, the 64-bit native integer is taken modulo 2³², i.e. the top 32 bits are lost. On 32-bit platforms, the conversion is exact.

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.

Same as of_string, but return None instead of raising.

• since 4.05

Return the string representation of its argument, in decimal.

An alias for the type of native integers.

The comparison function for native integers, with the same specification as Stdlib.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.

Same as compare, except that arguments are interpreted as unsigned native integers.

• since 4.08

The equal function for native ints.

• since 4.03

Return the smaller of the two arguments.

• since 4.13

Return the greater of the two arguments.

• since 4.13

A seeded hash function for native 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

An unseeded hash function for native 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
