How are the binary descriptors generated in OpenCV?

I have been working with the binary descriptors that are implemented in OpenCV. But the descriptors are formed with integer values (shown in red rectangle).

Why are they formed with integer values?

Say you have Orb binary descriptor which is 256 bit long. Then the bits are broken down into 8 bits and are converted to their base10 numerical representation. So 256 bit will be represented by array of 32 integers, and all those integer's value will be between 0 to 255.
