MATLAB Script for Dividing a Positive Number into Halves Successively Until the Result is Less Than 1

Question:

How to write a Matlab code which successively halves a number (>=1; positive), entered by the user until the result is less than 1. The program should print out the first number, and then the values each time it is successively halved.

Answer:

The probelm can be solved using while loop. The code is given below:

clear all; clc; close all
a = input('Enter a positive number greater than 1: ');
i = 1;
fprintf('#\tsuccessive Division\n')
while a > 2
    a_half = a/2;
    a = a_half;
    fprintf('%d\t\t%f\n',i,a_half)
    i = i + 1;
end
    disp('The number is less than 1')

OUTPUT

Enter a positive number greater than 1: 
119
#	successive Division
1		59.500000
2		29.750000
3		14.875000
4		7.437500
5		3.718750
6		1.859375
The number is less than 1
