Also called Q-formatFractional representation suitable for DSP algorithms.Fractional number range is between 1 and -1 Multiplying a fraction by a fraction always results in a fraction and will not produce an overflow (e.g., 0.99 x 0.9999 less than 1) Successive additions may cause overflow Represent numbers between
-1.0 and 1 − 2− ( N-1), when N is number of bits
