Acron RPN announces v3.0 BETA

Thank you all, for inspiring my continued education. Today's subject: integral algorithms.

Riemann/Trapezoid: I set up a quick Excel spreadsheet, solving \(\int_{1}^{2}e^x dx\) 4096 steps, and I still had a error of 23.2E-9
Simpson rule was next, and 32 steps had the error down to 24.7E-9.

Now, if I can just wrap my head around Romberg's Method [as explained on Wikipedia] without my brain melting, I'll consider myself educated. For today, anyway.
