I'm going to be scattering my answer across comments so I decided to answer this one because I thought it was interesting.
In the context of money, we do not say the point: $1.43 becomes "one forty three". It could also be many other things, like "a buck forty three", et cetera.
In the context of anything else, we would say the point: "one point four three" and "one point forty three" are both acceptable. There may be regionality in this, but if the number of digits after the point is only two, it is very common for me to hear and say the composite "one point forty three". If it is more than two, this will never be done.
