MATLAB: Uint8 to double is converting pixel values into decimal

Image Processing Toolboxuint

when I convert my image which is in uint format to double the pixel matrix values are converting into decimal values
These are uint matrix of image
   181  185  165  128  109  143  163  159  160  164  182  177  179  182  185  187  193  193
and these are double values of same image
0.709803921568628  0.725490196078431  0.647058823529412  0.501960784313726  0.427450980392157  0.560784313725490  0.639215686274510  0.623529411764706  0.627450980392157  0.643137254901961
why is this happening so? whats the solution

Basically it's dividing by 255 when you use im2double(). If you don't want that, then don't do it. If you want the floating point version but the values to be the same, use double() instead of im2double().
