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.
