The domain remark was, although correct, already pretty much besides the point but this misses it completely: I wrote mathematical example because this was meant to be a mathematical example. Provided that 1/n is defined, that is n is not 0, x / (1 / n) is by definition the same as x * n. That's 6th form (in Germany) fractional arithmetic: Dividing a fraction by another fraction is accomplished by the first fraction by the inverse (German: Kehrbruch, no idea how that's called in English) of the second and everybody "whose brain is wired correctly" ought to understand that. But inverting the expression in this way is nevertheless a simple form a steganography. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
