Class type

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

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

of_string and t_of_sexp disallow nan, inf, etc.

val of_string : string -> t
val to_string : t -> string

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

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 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 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 -> Core_kernel__.Import.Validate.t
