WebOct 7, 2003 · First, determine the maximum absolute value M that you wish to calculate for each class of fixed-point variable. The value of M for each example requirement is 1, 100, and 1,000, respectively. Second, calculate the number of bits x required to store this number such that 2 x M 2 x -1 . If the number is to be signed, add 1 to x .
