OK, this is the new approach:

The problem with this one is that in some cases, we are not stopping when we
should. For example:
$ seq 1.7 .7 10
1.7
2.4
3.1
3.8
4.5
5.2
5.9
6.6
7.3
8
8.7
9.4 <--- Should have stopped here
10.1
$ seq 1.07 .07 10
...
...
9.96 <--- Should have stopped here
10.03
I attached a new test file "output_incr_over_two.txt"
