Isn't this related to http://www.diycalculator.com/sp-round.shtml#A3 ?

BTW, the following function 'corrects' Pythons arithmetic rounding:

def roundf(f, prec=0):
    return round(f + (.1 / pow(10, prec + 2)), prec)

Title:
  rounding error

Status in OpenERP Server:
  New

Bug description:
  Concerns 6.0 and trunk.
  If you define a precision of 0.01, the rounding of 0.125 must be 0.13 and not 0.12. The error is in the call of the format string "%.2f"%val which introduces a mathematical error. The round function must be called to apply the correct rounding before formatting the string. It should be:
  "%.2f"%round(val*100)/100
  Fix class digits_change of class float in the server. BUT fix also the gtk client AND web client as they all have that error (I let you find the right line)
