Re: [sympy] sympy.core.numbers.Float with numpy.fft

[krastano...@gmail.com]

This is basically a characteristic of numpy. sympy.Float supports the
interfaces required from a float-like object, namely the __float__
method. Numpy does not look for this, so you should explicitly require
numpy to use the float64 dtype.

In [5]: a = sin(1).evalf(), sin(2).evalf()
In [6]: np_a = np.array(a, dtype=np.float64)

And sympy has a new plotting module that may fulfill your needs. Check
it out if you are interested. It is in our git repository.

Thanx for the replay. I'm using your solution.

As for the plotting module, i'm trying to settle down with matplotlib.

Good idea. That is why the plotting module actually uses matplotlib.
It just does all the evaluations, etc automatically for you (in a
faster manner than what you get by using .evalf())
