Is there a way to produce random numbers with different decimal lengths?

You can use another call to RAND to generate the integers 0-3, and then use that as an input to the ROUND function, e.g.:

data have(keep=group val places val2);
  a=-5; b=5;
  do i=1 to 100;
    do group="grp1", "grp2", "grp3";
      u=rand("Uniform");
      val=a+(b-a)*u;
      places = rand("Integer", 0, 3);
      val2=round(val,10**(places*-1)) ;
      output;
    end;
  end;
run;

proc print data=have ;
run ;

Note that as mentioned when you PRINT the rounded data you won't see values varying number of places, because SAS is still storing them all as numbers.  If you want to actually see values with varying number of places, you might want to consider converting this variable to character.  But it all depends on what your macro is designed to do.

Thanks for your help, Quentin!
