1. Needs be compacted in function form.
2. Very poor integrator. Hardly improves Smath operator.
3. Slow to useless.
4. I don't understand (dint-dintp)/15 ?

5. exp(sqrt(x)) was chosen for it's innocent look
but difficult to integrate c/w sanity check.
6. Observe Romberg [f, limits] => for high accuracy.

Integrate SimpsonRichardson.sm (25 KiB) downloaded 40 time(s).

Needs a proof of utility by application.

Simpson-Richardson is not a good choice.

I think this is SMath file I made long time ago (not sure). I was just playing with it.
