Wrong result from example in the docs if integer args

[ggventurini]

Hi,

I am trying out pyautodiff and I ran into the following problem:

from autodiff import gradient

@gradient
def f(x):
    return x**2

print(f(100))

Prints out:

0.0

Which is wrong.

Instead if I call print(f(100.)) -- notice the dot, which makes the argument a float -- I get the correct result:

200.0

Am I missing something? Am I doing something wrong?

Thanks for all the good work!

GV
