I don't speak about currency conversion.

You have to use `is_zero` on the holding's currency instead of `openerp.tools.float_is_zero`.

Here is the method I speak about:

    def is_zero(self, cr, uid, currency, amount):
        """Returns true if ``amount`` is small enough to be treated as
           zero according to ``currency``'s rounding rules.

           Warning: ``is_zero(amount1-amount2)`` is not always equivalent to
           ``compare_amounts(amount1,amount2) == 0``, as the former will round after
           computing the difference, while the latter will round before, giving
           different results for e.g. 0.006 and 0.002 at 2 digits precision.

           :param browse_record currency: currency for which we are rounding
           :param float amount: amount to compare with currency's zero
        """
        return float_is_zero(amount, precision_rounding=currency.rounding)
