Public bug reported:

At this time, OpenERP works, but I found a peculiar problem. This is
the scenario, creating a budget:

Tax: 12.5%

Product: XYZ
Product Price: 50.00
Product Size: 1.00 

That is: Real World:  50.00 * 1.00 = 50.00, in OpenERP 50.00 * 1.00 =
50.15$

Later
But the SubTotal is 5.90
Tax Total: 5.90
Total: 56.05

Equal, in the Real World the tax 50.15$ * 0.125 (%) = 6.27$ in OpenERP
50.15$ * 0.125 (%) = 5.90$!!!!!!


It makes no sense that if a product costs $ 50.00 per item, the subtotal of $ 50.15 for a single (1) piece. Still less, that the error is propagated with a tax of 12.5% giving a total tax of $ 5.90. To that end, the total of all the calculation of $ 56.05.

Some of the comments argue that users should adjust prices to go even
"square" in quotes, values. This is absolute nonsense, taking into
account the great responsibility that must have ERP software in the
reliability of its results and operations.

Please, should you make any adjustment of the code? It is an irreparable
error? What is the strategy recommended to resolve the situation?
