 Is this what you're getting at?
 
 echo f001 f00d | awk '{ a="0x" $1; b="0x" $2; while (a < b) { print a; a++; }}'
 0xf001
 
 vs.
 
  echo f001 f00d | awk '{ a="0x" $1; b="0x" $2; a+=0; b+=0; while (a < b) { 
print a; a++; }}'

 sprintf witih %d doesn't produce an number value; it produces a
 string value, which you have to coerce to a number by adding zero to
 it to get it to behave like a number.
