Hallo "Anonymous", ich benutze aus Bequemlichkeit meist die Potenzschreibweise:
$${\mathtt{9.42}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{12}}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{4}}} = {\mathtt{1\,130\,400\,000\,000\,000\,000}}$$
$${\mathtt{9\,420\,000\,000\,000}}{\mathtt{\,\times\,}}{\mathtt{120\,000}} = {\mathtt{1\,130\,400\,000\,000\,000\,000}}$$
9,42*12*10^16 = 113,04*10^16 = 1 130 400 000 000 000 000
