Module CCFloat

Basic Float functions

type t = float
type fpclass = Pervasives.fpclass =

| FP_nan
val nan : t
val max_value : t
val min_value : t
val max_finite_value : t
val epsilon : t
val is_nan : t ‑> bool

val pp : t printer
val hash : t ‑> int
val random : t ‑> t random_gen
val random_small : t random_gen
val random_range : t ‑> t ‑> t random_gen
val fsign : t ‑> t

fsign x is one of -1., -0., +0., +1., or nan if x is NaN.

val round : t ‑> t

round f returns the closest integer value, either above or below

exception TrapNaN of string
val sign_exn : t ‑> int

sign_exn x will return the sign of x as 1, 0 or -1, or raise an exception TrapNaN if x is a NaN. Note that infinities have defined signs in OCaml.

val to_int : t ‑> int

Alias to int_of_float. Unspecified if outside of the range of integers.

val of_int : int ‑> t

Alias to float_of_int

val to_string : t ‑> string
val of_string_exn : string ‑> t

Alias to float_of_string

val of_string : string ‑> t

Alias to float_of_string.

val equal_precision : epsilon:t ‑> t ‑> t ‑> bool

Equality with allowed error up to a non negative epsilon value

val classify : t ‑> fpclass
