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 equal : t -> t -> bool
val compare : t -> t -> int
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 is_positive : t -> bool
val is_non_negative : t -> bool
val is_negative : t -> bool
val is_non_positive : t -> bool
val sign : t -> Sign0.t

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

val neg : t -> t
val abs : t -> t
val is_zero : t -> bool
val is_nan : t -> bool
val is_inf : t -> bool
val apply : t -> float -> float

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

val scale : t -> float -> t

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

val of_mult : float -> t

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

val to_mult : t -> float
val of_percentage : float -> t

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

val to_percentage : t -> float
val of_bp : float -> t

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