(format "%d" #xff) ; hex to decimal
--> "255"
(format "%x" 255) ; decimal to hex
--> "ff"
(format "%d" #o644) ; octal to decimal
--> "420"
(format "%o" 420) ; decimal to octal
--> "644"
And didn't Pascal B. point this out in the thread previously cited?
(format "#8r%o #10r%d #16r%x" 42 42 42)
--> "#8r52 #10r42 #16r2a"
