Enforce all numbers to use the same type
Created by: dvkt
I think the to_string() was producing something different for ints and the number type, so casting them all to the same type fixed the quine for me.
However I couldn't get any warnings on Linux even when the quine was broken so I'm not sure if this will fix the issue you mentioned in #22. What compiler are you using? I have gcc (GCC) 8.2.1 20190131.
