No, but googling for "inverse error function" yields the page
http://home.online.no/~pjacklam/notes/invnorm/ which describes a good
algorithm and lists implementations in many languages (including bc
and Visual Basic!). You should have no difficulty writing your own in
Common Lisp from the description or translating one of the other
implementations. Maybe you could contribute it to that page
afterwards?
