A uint16 is a 16-bit unsigned integer. You can read lots and lots of details about data types in MATLAB on this page: http://www.mathworks.com/help/matlab/data-types_data-types.html.
The default data type for most MATLAB calculations is "double", a double-precision real number. To convert a uint16 to a double:
x = double(xu16)
The meaning of the type UINT16 is explained in:

While UINT16 variables can contain integer values between 0 and 2^16-1, they are displayed as decimal numbers as doubles, singles and the other integer types also. Binary or octal numbers would be non-decimal.
