What Albert wrote implies that precision is 0.005 (half of 0.01).
But (what he did not wrote) default unit for mechanical work is
milimeter.  0.005 of milimeter is 5 micron.

Agreed, the terms mu and micron are still quite popular among boomers,
but haven't actually been part of the SI since 1967. It's micrometre,
folks. Glow up!

 
Irrelevant. Albert pointed out that the number "1.00" means nothing
without a context that allows to decide how the number should be
printed or evaluated.
...

But we do know something about it in the context of computer math.
For ex. "1.00" when presented to a computer will be extended to the
intrinsic precision of the computer's floats and be used thereafter
at that precision.  Similarly when it comes to output an fp number
to an external device it will be at the intrinsic precision unless
reduced by the operator.
