RE: HP48-HP50G : Error functions ERF(z), FRESNEL integrals, PROBIT, etc.

Version 9f

In the previous versions 9, the simplification of the input argument was incorrect when in presence of a complex arguments z=a+ib, with b≠0 (but everything was correctly calculated).

Now the 'arg.num' subroutine was duly fixed up.

Please note for INVERSE_ERF, called 'INV¦',
when using complex argument z=a+ib, b≠0,
that the results are quite accurate for abs(argument z) < 0.91.

Please note that this last uploaded version 9f
has a "print" error at variable VERSIO.

Please change it
