Class type

A scale factor, not bounded between 0% and 100%, represented as a float.

type t
include sig ... end
val hash_fold_t : Base.Hash.state -> t -> Base.Hash.state
val hash : t -> Base.Hash.hash_value

of_string and t_of_sexp disallow nan, inf, etc.

include Interfaces.Stringable with type t := t
val of_string : string -> t
val to_string : t -> string

Sexps are of the form 5bp or 0.05% or 0.0005x

include Interfaces.Sexpable with type t := t
include sig ... end
include Interfaces.Binable with type t := t
include Bin_prot.Binable.S_only_functions with type t := t
val bin_size_t : t Bin_prot.Size.sizer
val bin_write_t : t Bin_prot.Write.writer
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val clamp : t -> min:t -> max:t -> t Base.Or_error.t

include Comparable.With_zero with type t := t
val validate_positive : t Base.Validate.check
val validate_non_negative : t Base.Validate.check
val validate_negative : t Base.Validate.check

val is_positive : t -> bool
val is_non_negative : t -> bool
val is_negative : t -> bool
val is_non_positive : t -> bool
val sign : t -> Base__.Sign0.t

Returns Neg, Zero, or Pos in a way consistent with the above functions.

include Robustly_comparable.S with type t := t
val (>=.) : t -> t -> bool
val (<=.) : t -> t -> bool
val (=.) : t -> t -> bool

val is_zero : t -> Base.Bool.t
val is_nan : t -> Base.Bool.t
val is_inf : t -> Base.Bool.t
val apply : t -> Base.Float.t -> Base.Float.t

apply t x multiplies the percent t by x, returning a float.

val scale : t -> Base.Float.t -> t

scale t x scales the percent t by x, returning a new t.

val of_mult : Base.Float.t -> t

of_mult 5. is 5x = 500% = 50_000bp

val to_mult : t -> Base.Float.t
val of_percentage : Base.Float.t -> t

of_percentage 5. is 5% = 0.05x = 500bp

val to_percentage : t -> Base.Float.t
val of_bp : Base.Float.t -> t

of_bp 5. is 5bp = 0.05% = 0.0005x

val to_bp : t -> Base.Float.t
val of_bp_int : Base.Int.t -> t
val to_bp_int : t -> Base.Int.t

rounds down

val t_of_sexp_allow_nan_and_inf : Sexp.t -> t
val of_string_allow_nan_and_inf : Base.String.t -> t
module Format : sig ... end

A Format.t tells Percent.format how to render a floating-point value as a string, like a printf conversion specification.

val format : t -> Format.t -> Base.String.t
val validate : t -> Base.Validate.t
module Stable : sig ... end
