Overflow Error in Python's numpy.exp function
<p>I want to use <code>numpy.exp</code> like this:</p>

<pre><code>cc = np.array([
    [0.120,0.34,-1234.1]
])

print 1/(1+np.exp(-cc))
</code></pre>

<p>But this gives me error:</p>

<pre><code>/usr/local/lib/python2.7/site-packages/ipykernel/__main__.py:5: RuntimeWarning: overflow encountered in exp
</code></pre>

<p>I can't understand why? How can I fix this? It seems the problem is with third number <code>(-1234.1)</code></p>
