Hi!
I run into Python error in rounding and not know how to predict when it will
occur in order to prevent wrong result.
What can I do to assure accurate result?
>>> "%.2f" % 0.445
'0.45' correct
>>> "%.2f" % 0.455
'0.46' correct
>>> "%.2f" % 0.465
'0.47' correct
>>> "%.2f" % 0.475
'0.47' not correct
>>> "%.2f" % 0.485
'0.48' not correct
>>> "%.2f" % 0.495
'0.50' correct
