I am not sure whether you still have a problem. It is not strictly correct to say that to_f gives me whatever decimal places it believes are significant. A float will always contain as many digits as it can hold. Is the problem that you wish to display it to a certain number of digits? If so then you can use sprintf. Alternatively of course there is the question of whether you need to convert it to a float in the first place. Can you just keep it as BigDecimal?
