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
