Return the absolute value of its argument.

val max_int : t

The greatest representable 64-bit integer, 263 - 1 = 9_223_372_036_854_775_807.

val min_int : t

The smallest representable 64-bit integer, -263 = -9_223_372_036_854_775_808.

Infix operators

  • since 2.1
val (+) : t -> t -> t
val (-) : t -> t -> t
val (~-) : t -> t
val (*) : t -> t -> t
val (/) : t -> t -> t
val (mod) : t -> t -> t

val (>) : t -> t -> bool
val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (<) : t -> t -> bool
val equal : t -> t -> bool

The equal function for 64-bit integers. Like Pervasives.(=)xy).

val compare : t -> t -> int

The comparison function for 64-bit integers, with the same specification as Pervasives.compare. Along with the type t, this function compare allows the module CCInt64 to be passed as argument to the functors Set.Make and Map.Make.

val hash : t -> int

Like Pervasives.abs(to_intx).

Conversion

val to_int : t -> 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.

val of_int : int -> t

Alias to Int64.of_int. NOTE: used to return an option, but the function actually never fails.

val of_int_exn : int -> t
  • deprecated use Int64.of_int instead
val to_int32 : t -> 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.

val of_int32 : int32 -> t

Alias to Int64.of_int32. NOTE: use to return an option, but the function actually never fails.

val of_int32_exn : int32 -> t
  • deprecated use Int64.of_int32 instead
val to_nativeint : t -> 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.

val of_nativeint : nativeint -> t

Alias to Int64.of_nativeint. NOTE: use to return an option, but the function actually never fails.

val of_nativeint_exn : nativeint -> t
  • deprecated use Int64.of_nativeint instead
val to_float : t -> float

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

val of_float : float -> t

Alias to Int64.of_float. 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 [CCInt64.min_int, CCInt64.max_int]. NOTE: used to return an option, but the function never fails.

val of_float_exn : float -> t
  • deprecated use Int64.of_float instead
val to_string : t -> string

Return the string representation of its argument, in decimal.

val of_string : string -> t option

Safe version of of_string_exn.

val of_string_opt : string -> t option

Alias to of_string.

  • since 2.1
val of_string_exn : string -> t

Alias to Int64.of_string. 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*CCInt64.max_int+1]. If the input exceeds CCInt64.max_int it is converted to the signed integer CCInt64.min_int + input - CCInt64.max_int - 1.

The _ (underscore) character can appear anywhere in the string and is ignored. Raise Failure "Int64.of_string" 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.
