How do change decimal place in command window?

I found a code that rounds any element of an array to any decimal place without using built in functions. It works good, but all the results in the command window are expressed in 10^-3. What needs to be done to express the results in their initial value.

Here's the code, so you can run it and see what I'm talking about.

clc;clear;format compact
numbers=[934.9 -0.4567 1045.76]; %get the number array
digits=[100 0.1 10];  %get the digit array
result=0*numbers;
% result=RoundTo(numbers, digits); % use function RoundTo to round array of numbers
for count0=1:length(numbers)
 number=numbers(count0);
 digit=digits(count0);
 num_sign=1;  % save the sign of number
 if number<0 
     num_sign=-1;
 end
 GNumber=num_sign*number;
 GFactor=1/digit;% change all digit to 1 by multiply by GFactor
 GNumber=GNumber*GFactor;
 int_num=0;   %to save the integer part of GNumber

   %find the integer part of GNumber
   if GNumber>=1
      max_order=0;
      count=0;
      decimal=1; 
      factor=zeros(1,500);
      while decimal<GNumber % compare GNumber with decimal = 1, 10, 100, 1000......
          count=count+1;
          decimal=10*decimal;
      end
      max_order=count;
      count_order=max_order;
      Temp_GNumber=GNumber;
      CNumber=0;

      while decimal>=1  %determine factor is coresponded with each decimal
         decimal=decimal/10;
         count=0;
         CNumber=count*decimal;
         while CNumber<Temp_GNumber
             count=count+1;
             CNumber=count*decimal;
         end 
         if decimal>=1
            Temp_GNumber=Temp_GNumber-(count-1)*decimal;
            factor(count_order)=count-1;
            count_order=count_order-1;
         end
      end
      decimal=1;

      for count=1:max_order %caculate integer part base on factors are detemined
         int_num=int_num+decimal*factor(count);
         decimal=decimal*10;
      end
   end
   if (GNumber-int_num)>=0.5 
      int_num=int_num+1;
   end
   output=num_sign*int_num/GFactor; 
   result(count0)=output;
end
output0=[numbers,digits,result]   % display the result on the command screen of matlab

That code uses quite a number of built-in functions. For example, number < 0 uses the built-in function named "lt", and [numbers,digits,result] uses the built-in function named "horzcat".
