What makes you believe that?

    >>> from decimal import Decimal as d, ROUND_HALF_UP
    >>> (d('0.565') * 100).quantize(d(1), ROUND_HALF_UP) / 100
    Decimal('0.57')
    >>> (d('0.575') * 100).quantize(d(1), ROUND_HALF_UP) / 100
    Decimal('0.58')

Decimal also supports rounding directly, instead of doing arbitrary
computations:

    >>> d('0.565').quantize(d('0.01'), ROUND_HALF_UP) 
    Decimal('0.57')
    >>> d('0.575').quantize(d('0.01'), ROUND_HALF_UP)
    Decimal('0.58')

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)
