I don't think it is possible.  RRDtool uses your OS's
printf implementation *and* it does some syntax checking.
So, even *if* your OS's printf could display it as such
then still RRDtool will complain (I think).

However, if you write a (part of a) front end that generates
a string in the format you want then of course you can display
this.

You'd have to use a three-step process:
1) calculate the numbers using "rrdtool graph /dev/null" and no
   graphing options (ie use "PRINT", not "GPRINT")
2) format the numbers generated by (1) to your liking
3) generate a graph and use the strings generated by (2) inside
   the label (ie "LINE1:target#color:$label"
