Basic Float functions


Since 0.6.1

type t = float 
type fpclass = Pervasives.fpclass = 
| FP_normal
| FP_subnormal
| FP_zero
| FP_infinite
| 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 add : t -> t -> t
val sub : t -> t -> t
val neg : t -> t
val abs : t -> t
val scale : t -> t -> t
val min : t -> t -> t
val max : t -> t -> t
val equal : t -> t -> bool
val compare : t -> t -> int
type 'a printer = Format.formatter -> 'a -> unit 
type 'a random_gen = Random.State.t -> 'a 
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.
Since 0.7
val round : t -> t
round f returns the closest integer value, either above or below
Since 0.20
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.
Since 0.7
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
Since 1.2
Raises Failure in case of failure
val of_string : string -> t
Deprecated.since 1.2, use CCFloat.of_string_exn instead
Alias to float_of_string.
Raises Failure in case of failure
val equal_precision : epsilon:t -> t -> t -> bool
Equality with allowed error up to a non negative epsilon value
val classify : t -> fpclass
