Abstract: In the method for coding/decoding a target range from a value range, a recurrence step is repeated in a coding/decoding step for the target range until code bits are found for the target range to be coded, or the target range to be decoded is found using the code bits. In the recurrence step, an interval of the value range within which the target range to be coded/decoded is located is divided into two new intervals, and a single bit is used to indicate in which of the two new intervals the target range to be coded/decoded is located. The new interval indicated with the single bit is used as the interval for the next recurrence step. The code bits for the target range to be coded or the target range to be decoded is found when the interval falls below a minimum quantity. In at least one recurrence step, a probability distribution is used as the basis for the target range in the interval, and the new intervals are selected based on the probability distribution.
