BTW, FYI, the "NaN" or "inf" magic is the magic of IEEE floating point
arithmetic (simply by using "double"). See these refs (into glibc documentation)
for details:
However, that's not the most portable thing and maybe it behaves differently on
the Neo ARM and on the PC, we should only be comfronted to "inf" and not "NaN"
in fact. (Notice that: -1/0 = -inf or 1/0=inf on my PC.)
If you confirm you get the NaN indication, I'll update "update_display" to
detect these case and display something but then I'll need you again to double
