    Norlin> the number actually comes from multiplication between 237.50 and
    Norlin> 4.762 which will get 1130.975. So it suppose to be 1130.98 isnt
    Norlin> it if it'll get rounded to 2 decimal places.

Nope.  1130.975 is not exactly representable.  In fact, it's internal
representation is slightly less that 1130.975, so rounding to two decimal
places is correctly 1130.97.
