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

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

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.
