【Abstract】 The computing orbit of the Logistic chaotic equation in computer system will deviate from the original orbit due to the effective precision of computer floating-point operation.The real orbit of the Logistic chaotic equation is analyzed and the experiment shows that it is difficult to compute the real orbit in the current computer system; the relationship between the IEEE 754 floating-point operation standard and the effective precision in the calculation system is analyzed and shows that firstly the computing orbit of the Logistic chaotic equation and the real orbit increase with iteration, the computing orbit is gradually separated from the real orbit; secondly, the effective precision of the computer significantly affects the separation speed between the computing orbit and the real orbit of the Logistic chaotic equation.更多还原
