The validate_* functions always fail if class is Nan or Infinite.

The results of robust comparisons on nan should be considered undefined.

validate_ordinary fails if class is Nan or Infinite.

min_positive_subnormal_value = 2 ** -1074 min_positive_normal_value = 2 ** -1022

If f <= iround_lbound || f >= iround_ubound, then iround* functions will refuse to round f, returning None or raising as appropriate.

includes positive and negative Float.infinity

min and max that return the other value if one of the values is a nan. Returns nan if both arguments are nan.

Returns the fractional part and the whole (i.e. integer) part. For example, modf (-3.14) returns { fractional = -0.14; integral = -3.; }!

mod_float x y returns a result with the same sign as x. It returns nan if y is 0. It is basically let mod_float x y = x -. float(truncate(x/.y)) *. y not let mod_float x y = x -. floor(x/.y) *. y and therefore resembles mod on integers more than %.

A sub-module designed to be opened to make working with floats more convenient.

Like to_string, but guaranteed to be round-trippable.

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 less) of them.

Pretty print float, for example to_string_hum ~decimals:3 1234.1999 = "1_234.200" to_string_hum ~decimals:3 ~strip_zero:true 1234.1999 = "1_234.2" . No delimiters are inserted to the right of the decimal.
