Hi,
I think the problem is deeper ...
>From python console :

s = 0.555 -> round(s*100)/100 = 0.56 OK
s = 0.585 -> round(s*100)/100 = 0.59 OK
s = 0.595 -> round(s*100)/100 = 0.60 OK

but :

s = 0.565 -> round(s*100)/100 = 0.56 NO (0.57 is correct)
s = 0.575 -> round(s*100)/100 = 0.57 NO (0.58 is correct)

The round issue is a python bug (not a OpenERP bug) ?! Or not ?

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)
