<p style="color: grey"> Python recipe 580762 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/binary/">binary</a>, <a href="/recipes/tags/formats/">formats</a>, <a href="/recipes/tags/integers/">integers</a>, <a href="/recipes/tags/numbers/">numbers</a>, <a href="/recipes/tags/representation/">representation</a>, <a href="/recipes/tags/type/">type</a>). </p> <p>This recipe shows how to find, via Python code, the number of bits needed to store an integer, and how to generate its binary representation. It does this for integers from 0 to 256.</p> <p>More details and full output here:</p> <p><a href="https://jugad2.blogspot.in/2017/03/find-number-of-bits-needed-to-store.html" rel="nofollow">https://jugad2.blogspot.in/2017/03/find-number-of-bits-needed-to-store.html</a></p>
