Algol68 has the type BITS, that is converted to INT with the ABS
operator.

"r" is for radix: http://en.wikipedia.org/wiki/Radix

The standard supports 2r, 4r, 8r & 16r only.

The standard supports LONG BITS, LONG LONG BITS etc, but does not
include UNSIGNED.

Compare gcc's:

bash$ cat num_lit.c
#include <stdio.h>
main(){
  printf("%d %d %d %d\n",0xffff,07777,9999,0b1111);
}

bash$ ./num_lit
65535 4095 9999 15


With Algol68's: https://sourceforge.net/projects/algol68/

bash$ cat num_lit.a68
main:(
  printf(($g$,ABS 16rffff,ABS 8r7777,9999,ABS 2r1111,$l$))
)

bash$ algol68g ./num_lit.a68
     +65535      +4095      +9999        +15

Enjoy
