RE: HP48-HP50G : Error functions Erf(x), Erfc(x) & Erf/Erfc —>x
The problem with that formula is the term ((2*n+1)*n! which rapidly grows into numbers with more than 12 digits. Large rounding errors are thus inevitable. I don't know offhand what algorithm the Prime uses but it probably comes from Xcas/GIAC which is open source.
