You are seeing an artifact of the fact that floating point numbers
cannot exactly represent decimal numbers.  The repl is printing out
the full precision of the numbers.  If you are interested in
formatting the numbers nicely, you can do something like this:

user> (map #(format "%.2f" %1) (range 0.05 0.16 0.01))
("0.05" "0.06" "0.07" "0.08" "0.09" "0.10" "0.11" "0.12" "0.13" "0.14"
"0.15")

Doing math with floating point numbers is generally fine, unless you
have need for very high accuracy.  Just format the final output when
you want to display it.
