# Description
As explained in the ticket, easy to reproduce. Example: 1.07 minute is
1.07*60=64.2 secondes
```nushell
# before - wrong
> 1.07min
1min 4sec
# now - right
> 1.07min
1min 4sec 200ms
```
# User-Facing Changes
Bug is fixed when using ``into duration``.
# Tests + Formatting
Added a test for ``into duration``
Fixed ``parse_long_duration`` test: we gained precision 😄
