Module Stdlib.Int64

Instructions: Use this module in your project

In the IDE (CLion, Visual Studio Code, Xcode, etc.) you use for your DkSDK project:

Add the following to your project's dependencies/CMakeLists.txt:

Copy

DkSDKProject_DeclareAvailable(ocaml
    CONSTRAINT "= 4.14.0"
    FINDLIBS str unix runtime_events threads dynlink)
DkSDKProject_MakeAvailable(ocaml)

Add the Findlib::ocaml library to any desired targets in src/*/CMakeLists.txt:

Copy

target_link_libraries(YourPackage_YourLibraryName
     # ... existing libraries, if any ...
     Findlib::ocaml)

Click your IDE's Build button

Not using DkSDK?

FIRST, do one or all of the following:

Run:
Copy
```
opam install ocaml.4.14.0
```

Edit your dune-project and add:

Copy

(package
  (name YourExistingPackage)
  (depends
  ; ... existing dependenices ...
  (ocaml (>= 4.14.0))))

Then run:

Copy

dune build *.opam # if this fails, run: dune build

Edit your <package>.opam file and add:

Copy

depends: [
  # ... existing dependencies ...
  "ocaml" {>= "4.14.0"}
]

Then run:

Copy

opam install . --deps-only

FINALLY, add the library to any desired (library)and/or (executable) targets in your **/dune files:

Copy

(library
  (name YourLibrary)
  ; ... existing library options ...
  (libraries
    ; ... existing libraries ...
    ))

(executable
  (name YourExecutable)
  ; ... existing executable options ...
  (libraries
    ; ... existing libraries ...
    ))

val zero : int64

Subtraction.

valmul : ``int64->``int64-> int64

Multiplication.

valdiv : ``int64->``int64-> int64

raises Division_by_zero

if the second argument is zero. This division rounds the real quotient of its arguments towards zero, as specified for [Stdlib.(/)](../<stdlib/#val-( )="">).

</stdlib.html#val-(>

valunsigned_div : ``int64->``int64-> int64

Same as div, except that arguments and result are interpreted as unsigned 64-bit integers.

since 4.08.0

valrem : ``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.

valunsigned_rem : ``int64->``int64-> int64

Same as rem, except that arguments and result are interpreted as unsigned 64-bit integers.

since 4.08.0

valsucc : ``int64-> int64

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

valpred : ``int64-> int64

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

valabs : ``int64-> int64

Return the absolute value of its argument.

val max_int : int64

The greatest representable 64-bit integer, 2⁶³ - 1.

val min_int : int64

The smallest representable 64-bit integer, -2⁶³.

vallogand : ``int64->``int64-> int64

Bitwise logical and.

vallogor : ``int64->``int64-> int64

Bitwise logical or.

vallogxor : ``int64->``int64-> int64

Bitwise logical exclusive or.

vallognot : ``int64-> int64

Bitwise logical negation.

valshift_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.

valshift_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.

valshift_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.

valof_int : ``int-> int64

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

valto_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 2⁶³, i.e. the high-order bit is lost during the conversion. On 32-bit platforms, the 64-bit integer is taken modulo 2³¹, i.e. the top 33 bits are lost during the conversion.

valunsigned_to_int : ``int64-> ``int option

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 4.08.0

valof_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.

valto_float : ``int64-> float

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

valof_int32 : ``int32-> int64

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

valto_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 2³², i.e. the top 32 bits are lost during the conversion.

valof_nativeint : ``nativeint-> int64

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

valto_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 2³². On 64-bit platforms, the conversion is exact.

valof_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.

valof_string_opt : ``string-> ``int64 option

Same as of_string, but return None instead of raising.

since 4.05

valto_string : ``int64-> string

Return the string representation of its argument, in decimal.

valbits_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.

valfloat_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.

valcompare :t -> t -> int

The comparison function for 64-bit integers, with the same specification as Stdlib.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.

valunsigned_compare :t -> t -> int

Same as compare, except that arguments are interpreted as unsigned 64-bit integers.

since 4.08.0

valequal :t -> t -> bool

The equal function for int64s.

since 4.03.0

valmin :t -> t -> t

Return the smaller of the two arguments.

since 4.13.0

valmax :t -> t -> t

Return the greater of the two arguments.

since 4.13.0
