<p style="color: grey"> Python recipe 577821 by <a href="/recipes/users/4172944/">Steven D'Aprano</a> (<a href="/recipes/tags/integer/">integer</a>, <a href="/recipes/tags/isqrt/">isqrt</a>, <a href="/recipes/tags/math/">math</a>, <a href="/recipes/tags/mathematics/">mathematics</a>, <a href="/recipes/tags/maths/">maths</a>, <a href="/recipes/tags/root/">root</a>, <a href="/recipes/tags/square/">square</a>). </p> <p>The <em>integer square root</em> function, or isqrt, is equivalent to floor(sqrt(x)) for non-negative x. For small x, the most convenient way to calculate isqrt is by calling int(x**0.5) or int(math.sqrt(x)), but if x is a large enough integer, the sqrt calculation overflows.</p> <p>You can calculate the isqrt without any floating point maths, using just pure integer maths, allowing the function to operate with numbers far larger than possible with floats:</p> <pre class="prettyprint"><code>&gt;&gt;&gt; n = 1234567*(10**1000) &gt;&gt;&gt; n2 = n*n &gt;&gt;&gt; math.sqrt(n2) Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; OverflowError: long int too large to convert to float &gt;&gt;&gt; isqrt(n2) == n True </code></pre>

Revision 3. </p> <p>This module allows the user to create a more verbose set of ranges. Simple character ranges, and float ranges are supported.</p> <p>Supported Ranges:</p> <ul> <li>Basic Integer Ranges</li> <li>Float Ranges (as accurate as a float range can get)</li> <li>Simple character ranges (lowercase to lowercase, uppercase to uppercase, etc.)</li> </ul> <p>It should work in Python 2 and Python 3.</p> <p><strong>If you tested this for speed, or want to test this for speed, please post the results! (And your system specs)</strong></p> <p><strong>Edit:</strong> Found a really silly error of mine when using range instead of xrange in these functions!</p>

<p style="color: grey"> Python recipe 576847 by <a href="/recipes/users/4166412/">Vishal Sapre</a> (<a href="/recipes/tags/binary/">binary</a>, <a href="/recipes/tags/decimal/">decimal</a>, <a href="/recipes/tags/integer/">integer</a>, <a href="/recipes/tags/string/">string</a>). </p> <p>This is a very simple look-up based method for converting integer to binary string. In my tests, using 'timeit', its the fastest around. And with increasing value of input decimal number, it surpases any 'run time computation' based method doing the above.</p>
