I am trying to convert fractional decimal number into binary. having done conversion with integer and fractional part I want to finally add them and show the result. I am getting following result. Please guide me what is wrong with the code?

clear all
clc
N = input('Enter the decimal number - ');
%B = input('Enter the base - ');
int = floor(N); %integer part
V = N - int; %decimal part
i = 1;
while(int > 0)
  R(i) = rem(int,2);
  int = floor(int/2);
  i = i+1;
end
b_n = fliplr(R);
disp('Binary equivalent of number is ');
disp(b_n);
x = 0;
k = 0.1;
while(V ~= 0)
  V = (V-floor(V))*2;
  x = x + floor(x + V)*k;
  k = k/10;
end
f_n = V + x;
disp(f_n);
C = b_n + f_n;
disp(C)

output

Enter the decimal number - 100.25
Binary equivalent of number is 
     1     1     0     0     1     0     0
      0.0100
    Columns 1 through 6
      1.0100    1.0100    0.0100    0.0100    1.0100    0.0100
    Column 7
      0.0100
