Rounding Issues in format duration

[fennewald]

Describe the bug

Formatting fractional durations appears to do some weird intermediate rounding.

How to reproduce

• 1.07min | format duration ms returns 64000 ms, despite the correct answer being 64200 ms.
• 1.07 min | format duration sec return 64 sec, and not the correct 64.2 sec.

Expected behavior

Correctly format durations, accounting for the precision of the output unit.

Interesting, related note: 1.07min / 1sec returns 64, not 64.2

[fennewald]

and 1.07min / 1ms returns 64000, and not the correct 64200. Perhaps it is not format duration, but nushell's internal duration math itself

Sounds like floats aren't handled right?
