;; bits can be entered using radix notation ;; but they are long integers so by default they ;; display in decimal. (bit-and 2r1100 2r1001) ;;=> 8 ;; 8 = 2r1000 ;; here we see the same bits entered in decimal (bit-and 12 9) ;;=> 8

;; bits can be entered in hexidecimal (bit-and 0x08 0xFF) ;;=> 8 ;; bits can be show with Integer/toHexString (Integer/toHexString (bit-and 0x0108 0xFFFF)) ;;=> "108"

;; bits can also be shown with Integer/toBinaryString (Integer/toBinaryString 235) ;;=> "11101011" (Integer/toBinaryString 199) ;;=> "11000111" (bit-and 235 199) ;;=> 195 (Integer/toBinaryString 195) ;;=> "11000011" ;; 11101011 = 235 ;;& 11000111 = 199 ;;========== ;; 11000011 = 195

;; here is the truth table for AND (Integer/toBinaryString (bit-and 2r1100 2r1010) ) ;;=> "1000" ;; or 2r1000
