We're lucky Python's "round" already implements those stuff for us :)

I've build a test that check if the rounding function works for the
algorithm you provided (i've used log2, seems to run a little faster) -
and, most importantly fails when provided any of the previous
algorithms.

Title:
  Incorrect float rounding when setting float field with too high
  precision

Status in OpenERP GTK Client:
  Confirmed
Status in OpenERP Server:
  Confirmed
Status in OpenERP Server 6.0 series:
  Confirmed

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)
