I think you may be missing the point: 'i' will *never* be equal to 0.
You have to define appropriate epsilon (1.e-10 was just an example).

If you increment or decrement by 0.1, and if 1.e-10 is not "close
enough" for you, you need to think some more about what you are
actually trying to achieve and whether your algorithm ever halts.
