@bcmyers any update on the timeline for float support?

[jmsunseri]

kinda making me sad this isn't better by now given all the popularity of the crate.

Dont waste time to get this library work for floats with hacks like
fract() / trunk() and
(x * 1000).round() / 1000
and copysign etc etc.

I'll try this https://docs.rs/format_num/latest/format_num/ instead

@enomado any luck with format_num?
I am also looking for solution that works with f64.

@azzamsa looks like I came to thousands crate.

Standard float format, then separate digits as chars.
