It's a hack basically - bash uses long ints for variables; but using
the printf statement you can do something like:
for (( i=0; i<10; i++)); do echo 1.$(printf "%01d" $i); done
which will print out the sequence 1.0 - 1.9.

Alternatively, it might in the long run be easier to download and
compile the gnu coreutils package, install it in your home directory
and put it in your path.
