Accurate Bernoulli numbers on the 41C, or "how close can you get"?

So the idea is:
IF p < 0,5
THEN return QF(p)
ELSE return -QF(1-p)

BTW, Ángel: accurate results near 0 and 1 are easy to get if Sandmath would offer the complementary error function erfc(x) and its inverse - instead of erf(x). So what about ERFC and IERFC in a future release?

I now remember I did a BIOS update about 10 years ago. So the hardware must be even older. ;-)
