WebBinary Digit Escaping. Let F be a procedure that transforms a binary number X to Y. In F we go through digits from the Most Significant Bit (MSB) of X to its Least Significant Bit (LSB) and performs following operations: If MSB is 0, the transformation fails unless X is 0. If it ever finds two consecutive 0s in X, the transformation fails. WebSep 17, 2024 · If the tail starts with one and has only zeroes following it, then round up or down to make it end in zero. For example, the number 0.1001 1000 lies exactly midway between 0.1001 and 0.1010. The latter is the one that ends in zero (the only even digit in binary). Therefore it is rounded up to 0.1010.
