Fixed point and floating point numbers
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 . WebBecause a fixed-point data type represents numbers within a finite range, overflows and underflows can occur if the result of an operation is larger or smaller than the numbers in that range. In binary arithmetic, a processor might need to take an n-bit fixed-point number and store it in m bits, where m ≠ n. If m < n, the range of the number ...
