How many significant figures?
what is 3.1536e16 in sigfigs?
Also, if this is a calc read it probably means $${\mathtt{3.153\: \!6}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{16}}}$$
otherwise it may mean $${\mathtt{3.153\: \!6}}{\mathtt{\,\times\,}}{{\mathtt{e}}}^{{\mathtt{16}}} = {\mathtt{28\,023\,238.137\: \!473\: \!627\: \!147\: \!295\: \!9}}$$
