Floating-point representation and utilities.

max and min will return nan if either argument is nan.

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.

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 %.

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.
