Thanks for the advise, i made the test using timeit and your very
interesting method to import... Now i know how to use timeit simply ;-)
New results on 1000 float values randomized from -500.0 to +500.0.
Each test is timeit(1000)
sign_0 : 0.375
sign_1 : 0.444 (+18%)
sign_2 : 0.661 (+76%)
sign_3 : 0.498 (+33%)
It seems it don't change the relative results between the methods.
Using timeit make measure accurate and remove print/range footprints.
I also try Arnaud's proposition, it make sign_0 just a little better
