Using round function still price 34.50 round to 34 in Odoo10

Question

I'm using round value for floated price but still my price 34.50 is rounded to 34. It should be 35 when it reached to 34.50. Mainly its work fine but i don't understand why it is not working on 3000 price percentage discount is 1.15

I am also attaching screen and code also.

@api.one
@api.depends('discount_type','discount_rate','amount_total')
def _compute_discount(self):

    mod_obj = self.env['ir.model.data']
    amount_discount = 0.0
    if self.discount_type == 'percent':
        amount_discount = self.amount_untaxed * self.discount_rate / 100
    else:
        amount_discount = self.discount_rate

    self.amount_discount = round(amount_discount)

Thanks in advance

You have this result because in python 1.15*3000 = 34.4999999 and round of 34.4999 is 34
