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
val of_int : int -> t
val to_string : t -> string
val of_string : string -> t
val equal_precision : epsilon:t -> t -> t -> bool
Equality with allowed error up to a non negative epsilon value
