val to_string_12 : t -> Base.String.t

to_string_12 x builds a string representing x using up to 12 significant digits. It loses precision. You can use "%{Float#12}" in formats, but consider "%.12g", "%{Float#hum}", or "%{Float}" as alternatives.

val to_string : t -> Base.String.t

to_string x builds a string s representing the float x that guarantees the round trip, i.e., Float.equal x (Float.of_string s).

It usually yields as few significant digits as possible. That is, it won't print 3.14 as 3.1400000000000001243. The only exception is that occasionally it will output 17 significant digits when the number can be represented with just 16 (but not 15 or fewer) of them.

include Core_kernel.Quickcheckable.S with type t := t
val sign : t -> Core_kernel.Sign.t
  • deprecated [since 2016-01] Replace [sign] with [robust_sign] or [sign_exn]
val robust_sign : t -> Core_kernel.Sign.t

(Formerly sign) Uses robust comparison (so sufficiently small numbers are mapped to Zero). Also maps NaN to Zero. Using this function is weakly discouraged.

val gen_uniform_excl : t -> t -> t Core_kernel.Quickcheck.Generator.t

gen_uniform_excl lo hi creates a Quickcheck generator producing finite t values between lo and hi, exclusive. The generator approximates a uniform distribution over the interval (lo, hi). Raises an exception if lo is not finite, hi is not finite, or the requested range is empty.

The implementation chooses values uniformly distributed between 0 (inclusive) and 1 (exclusive) up to 52 bits of precision, then scales that interval to the requested range. Due to rounding errors and non-uniform floating point precision, the resulting distribution may not be precisely uniform and may not include all values between lo and hi.

gen_incl lo hi creates a Quickcheck generator that produces values between lo and hi, inclusive, approximately uniformly distributed, with extra weight given to generating the endpoints lo and hi. Raises an exception if lo is not finite, hi is not finite, or the requested range is empty.

gen_finite produces all finite t values, excluding infinities and all NaN values.

gen_positive produces all (strictly) positive finite t values.

gen_negative produces all (strictly) negative finite t values.

gen_without_nan produces all finite and infinite t values, excluding all NaN values.

val pretty : ?on_negative:[ `Blow_up | `Normal | `Print_dir ] -> float -> string

pretty-print a float using no more than five characters, using abberviations k, m, g, t.

if on_negative is not set to `Normal then the resulting is never over four chars but upon negative number we either:

  • raise a failure
  • or print "<0"
val to_string_hum : float -> string
val order_of_magnitude_difference : float -> float -> int

order_of_magnitude_difference a b by how many orders of magnitude do a and b differ? The return value is non-negative.

examples:

  • order_of_magnitude_difference 11. 1001. = 2
  • order_of_magnitude_difference 1001. 11. = 2
  • order_of_magnitude_difference 131. 11. = 1
  • order_of_magnitude_difference 200. 0.003 = 5
