it seems that these formaters are just defined constant :
#define B11111110 254
#define B11111111 255
in binary.h
so you could also define your own set, I suppose, for a whole 16bit integer. Don't forget to add some zeros, like here :
#define B1000 8
#define B01000 8
#define B001000 8
#define B0001000 8
#define B00001000 8
That would be a lot of constants !!
