Starting to assign initial values of variables from literals ...  done.
Now to print out those values ... n = 987654321 // k = 1.0E+37 done.
Now to try huge literal ... done, and to print out that value ... nb = 9.87654321E+307 done. I tried one digit larger literal, but it gave "Inf" (infinity) as the result. Let me try creating a similar value by arithmetic ... nbb = INF done.

i1 = 81212121212121
i2 = i1*1000000 = 8.1212121212121E+19
i3 = i2+i1 = 8.1212202424242E+19
i1b = i3-i2 = 81212121219072
