Title:
  Calculating failure rates and total precision error of rounding

Status in OpenERP Server:
  Invalid

Bug description:
  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?
