if you just use $1 for something like 07, then it will cut off the leading zero (which in this case, you need)
so might be best just to split everything into individual floats, like:
[ 1 9 7 8 0 7 2 9 0 9 3 0 2 1 (
and then just feed that into a big compound message like
[ $1$2$3$4$5$6$7$8$9$10$11$12$13$14 (
that way you get all the zeroes as well
