  • raises Invalid_argument

    if second argument (count) is negative

val shift_right : t -> t -> t
  • raises Invalid_argument

    if second argument (count) is negative

val shift_right_logical : t -> t -> t
  • raises Invalid_argument

    if any argument is negative

val logand : t -> t -> t
val logor : t -> t -> t
val logxor : t -> t -> t
val lognot : t -> t
val min : t -> t -> t
val max : t -> t -> t
val e_div : t -> t -> t

Euclidean division (that returns a positive rem). Implemented by Z.ediv

Equivalent to C division if both operands are positive. Equivalent to a floored division if b > 0 (rounds downwards), otherwise rounds upwards. Note: it is possible that e_div (-a) b <> e_div a (-b).

val e_rem : t -> t -> t

Remainder of the Euclidean division (always positive). Implemented by Z.erem

val e_div_rem : t -> t -> t * t

e_div_rem a b returns (e_div a b, e_rem a b). Implemented by Z.ediv_rem

val c_div : t -> t -> t

Truncated division towards 0 (like in C99). Implemented by Z.div

val c_rem : t -> t -> t

Remainder of the truncated division towards 0 (like in C99). Implemented by Z.rem

val c_div_rem : t -> t -> t * t

c_div_rem a b returns (c_div a b, c_rem a b). Implemented by Z.div_rem

val pgcd : t -> t -> t

pgcd v 0 == pgcd 0 v == abs v. Result is always positive

val ppcm : t -> t -> t

ppcm v 0 == ppcm 0 v == 0. Result is always positive

  • deprecated

    24.0-Chromium Renamed to to_int64_exn. Also consider using to_int64_opt.

val to_int32 : t -> int32
  • deprecated

    24.0-Chromium Renamed to to_int32_exn. Also consider using to_int32_opt.

  • since 24.0-Chromium
val to_int_opt : t -> int option

Returns Some i if the number can be converted to an int, or None otherwise.

  • since 24.0-Chromium
val to_int64_opt : t -> int64 option

Returns Some i if the number can be converted to an int64, or None otherwise.

  • since 24.0-Chromium
val to_int32_opt : t -> int32 option

Returns Some i if the number can be converted to an int32, or None otherwise.

val to_float : t -> float
val of_float : float -> t
val round_up_to_r : min:t -> r:t -> modu:t -> t

round_up_to_r m r modu is the smallest number n such that n>=m and n = r modulo modu

val round_down_to_r : max:t -> r:t -> modu:t -> t

round_down_to_r m r modu is the largest number n such that n<=m and n = r modulo modu

val two_power : t -> t

Computes 2^n

val two_power_of_int : int -> t

Computes 2^n

val power_int_positive_int_opt : int -> int -> t option

Exponentiation

val extract_bits : start:t -> stop:t -> t -> t
val popcount : t -> int
val hash : t -> int
val to_string : t -> string
val of_string : string -> t
  • raises Invalid_argument

    when the string cannot be parsed.

val pretty : t formatter

Prints the integer in decimal format. See also pretty_hex.

  • before 25.0-Manganese

    there was an optional hexa argument.

val pretty_hex : t formatter

Prints the integer in hexadecimal format (replaces hexa optional argument of pretty from older versions).

  • since 25.0-Manganese
val pp_bin : ?nbits:int -> ?sep:string -> t formatter

Print binary format. Digits are output by blocs of 4 bits separated by ~sep with at least ~nbits total bits. If nbits is non positive, it will be ignored.

Positive values are prefixed with "0b" and negative values are printed as their 2-complement (lnot) with prefix "1b".

val pp_hex : ?nbits:int -> ?sep:string -> t formatter

Print hexadecimal format. Digits are output by blocs of 16 bits (4 hex digits) separated by ~sep with at least ~nbits total bits. If nbits is non positive, it will be ignored.

Positive values are preffixed with "0x" and negative values are printed as their 2-complement (lnot) with prefix "1x".
