, convert 17.625 to a binary bit: 10001.101 (0.625 = 0.5 + 0.125, 0.5 is 1/2, 0.125 is 1/8) Then shift the decimal point of 10001.101 to the left until only one digit before the decimal point is 1.0001101x2 to the 4 power (because the four digits are shifted to the right ). In this case, the base number m and the index e come out:The base number is M. Because it must be 1 before the decimal point, IEEE requires that only the decimal point be recorded. Therefore, the base number is 0001101.Expone

process, there is such a figure: Then let's take a look at the NFA definition: M = (S, E, F, so, Z), which is the same as the definition of DFA.
