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 scale : t -> float -> t

negation

val (/) : t -> float -> t
val (//) : t -> t -> float
val to_short_string : t -> string

to_short_string t pretty-prints approximate time span using no more than five characters if the span is positive, and six if the span is negative. Examples

  • "4h" = 4 hours
  • "5m" = 5 minutes
  • "4s" = 4 seconds
  • "10ms" = 10 milliseconds

only the most significant denomination is shown.

module Unit_of_time : sig .. end
val to_unit_of_time : t -> Unit_of_time.t

to_unit_of_time t = Day if abs t >= day, Hour if abs t >= hour, and so on down to Microsecond if abs t >= microsecond, and Nanosecond otherwise.

val of_unit_of_time : Unit_of_time.t -> t

of_unit_of_time unit_of_time produces a t representing the corresponding span.

val to_string_hum : ?delimiter:char -> ?decimals:int -> ?align_decimal:bool -> ?unit_of_time:Unit_of_time.t -> t -> string

to_string_hum t ~delimiter ~decimals ~align_decimal ~unit_of_time formats t using the given unit of time, or the largest appropriate units if none is specified, among "d"=day, "h"=hour, "m"=minute, "s"=second, "ms"=millisecond, "us"=microsecond, or "ns"=nanosecond. The magnitude of the time span in the chosen unit is formatted by:

Float.to_string_hum ~delimiter ~decimals ~strip_zero:(not align_decimal)

If align_decimal is true, the single-character suffixes are padded with an extra space character. In combination with not stripping zeroes, this means that the decimal point will occur a fixed number of characters from the end of the string.

val randomize : t -> percent:float -> t

randomize t ~percent returns a span +/- percent * original span. Percent must be between 0 and 1, and must be positive.
