| Abstract: | Based on the indicated method of the fixed-point number and the floating-point number in computer area,the essay specified the indicated extent of the fixed-point number and floating-point number;it also emphasized and classified the misconception that while expressing the binary system number with the similar word length,the indicated range of floating-point numbers is larger than that of fixed-point numbers;meanwhile,it gave some examples to explain the specified situations how the range indicated by fixe... |
