Integers implementation. *

type t = Z.t
val zero : t
val one : t
val m_one : t
val compare : t -> t -> int
val compare_to_0 : t -> int
val equal : t -> t -> bool
val sign : t -> int
val hash : t -> int
val is_zero : t -> bool
val is_one : t -> bool
val is_m_one : t -> bool
val add : t -> t -> t
val sub : t -> t -> t
val mult : t -> t -> t
val div : t -> t -> t
val rem : t -> t -> t
val div_rem : t -> t -> t * t
val minus : t -> t
val abs : t -> t
val my_gcd : t -> t -> t
val my_lcm : t -> t -> t
val max : t -> t -> t
val from_int : int -> t
val from_string : string -> t
val to_string : t -> string
val pp_print : t Fmt.t
val to_machine_int : t -> int option

convert to machine integer. returns None in case of overflow

val to_float : t -> float
val fdiv : t -> t -> t
val cdiv : t -> t -> t
val power : t -> int -> t
val print : Stdlib.Format.formatter -> t -> unit
val shift_left : t -> int -> t

Shifts left by (n:int >= 0) bits. This is the same as t * pow(2,n)

val sqrt_rem : t -> t * t

returns sqrt truncated with the remainder. It assumes that the argument is positive, otherwise, Invalid_argument is raised.

val testbit : t -> int -> bool

testbit z n returns true iff the nth bit of z is set to 1. n is supposed to be positive

val numbits : t -> int

return the number of bits set to one in the given integer
