I created a new UoM called "Dos @ 12 Kg": Category weight and bigger than the reference UoM (Kg) with ratio = 12 with rounding precision 0.010
The system automatically changes its ratio to 12.000000000048

When I tried to deliver a product with this UoM, it causes a problem below:

The unit of measure rounding does not allow you to ship "100.0 Dos @ 12Kg", only rounding of "0.0 Dos @ 12Kg" is accepted by the Unit of Measure.

I have created other UoM similar to this "Dos @ 12Kg" but only this one is causing problems. What am I doing wrong?

Bigger than and Smaller Than: LET ME SEE YOU !!!  https://www.dropbox.com/s/goltw2x06h9bae2/Let me see you.png?dl=0

 

The Arithmetic (From the product.py):

Ratio  = 12

factor_inv = 1 / Ratio = 0.083333333333

1 / factor_inv = 1 / 0.083333333333 = 12,000000000048 = Ratio

 

Let's play now: With the Wrong Tooltip and the Double Inversion

After the Odoo updates on 08, 09 and 16 October 2014 this issue (and other issues related to UoM conversion) can be considered as (partially) solved.

Sorry for the error, now corrected: ZERO replaced by ONE in Greater than and Smaller than.
