Division by zero on Galculator ( calculator) shows "inf" (infinity). — However, note that the equation "x"*0=1 cannot have any solution at all (not even "inf") in any however extended nontrivial number system satisfying the associativity law, since else 1="x"*0="x"*(0*"n")=("x"*0)*"n"=1*"n"="n", for arbitrary "n".
