RE: RE: HP48-HP50G : Error functions ERF(x or z), ERFC (x or z) & iERF/iERFc —>x
Version 9d

Much more compact subroutine 'inv¦z' for inverse calculation of ERF & ERFc,
when argument z is a complex with abs(z) < 1 :
now, to save memory place, the coefficients in the formulae development used in 'inv¦z' derive also from a formulae.

Strongly recommended to use the EMU48 Android application, if you want to get the results within a couple of seconds.
