Hola Jens: "c) we have answered this several million times." - (I replied directly in order not to "spam" the forum.) Given, that this question is really so frequent: Couldn't it be possible that the manual ("THE BOOK") is not quite as explicit as it ought to be on this particular topic? (I made Lea Rebanks' experience with MATHEMATICA 2.x back in abt. 1992 - _after_ having read the manual cover to cover.) (Lea Reabanks intention/objective was to obtain the number without ANY parentheses.)
