Hi!
Re the VERY large number: yes. If the value reaches the maximum value
it's converted to NAN.
Re the most efficient way: look at the code-bit in the library. These
are only a couple of lines code. It might get faster if you just do a
copy and past into your code but I don't think it'll speed up much more.
A faster way is probably if you stay with integer values and don't
convert to floating point.
