### Literal syntax for integers

There are several ways to write literal integers with different radixes in Common Lisp. #b… is for binary, #o… is for octal, #x… is for hexadecimal, and #r is for an arbitrary radix from 2 to 36. Section 2.4.8.10 has this example:

#2r11010101 ;Another way of writing 213 decimal #b11010101 ;Ditto #b+11010101 ;Ditto #o325 ;Ditto, in octal radix #xD5 ;Ditto, in hexadecimal radix #16r+D5 ;Ditto #o-300 ;Decimal -192, written in base 8 #3r-21010 ;Same thing in base 3 #25R-7H ;Same thing in base 25 #xACCEDED ;181202413, in hexadecimal radix
