<p style="color: grey"> Bash recipe 578934 by <a href="/recipes/users/4177147/">Barry Walker</a> (<a href="/recipes/tags/arithmetic/">arithmetic</a>, <a href="/recipes/tags/bash/">bash</a>, <a href="/recipes/tags/check/">check</a>, <a href="/recipes/tags/checker/">checker</a>, <a href="/recipes/tags/cygwin/">cygwin</a>, <a href="/recipes/tags/macbook_pro/">macbook_pro</a>, <a href="/recipes/tags/math/">math</a>, <a href="/recipes/tags/mathematics/">mathematics</a>, <a href="/recipes/tags/perfect/">perfect</a>, <a href="/recipes/tags/root/">root</a>, <a href="/recipes/tags/square/">square</a>). </p> <p>A recent Python upload here gave me the inspiration to do a bash version... This is a little tongue-in-cheek but an enjoyable bit of fun.</p> <p>It took around 11 seconds to prove 90000000000 had a perfect square of 300000...</p> <p>It is a stand alone program and has a degree of INPUT error correction...</p> <p>It was done on a MacBook Pro, OSX 10.7.5, default bash terminal and should work on Linux flavours but it is untested...</p> <p>Enjoy finding simple solutions to often very difficult problems...</p> <p>Bazza...</p>

<p style="color: grey"> Python recipe 578528 by <a href="/recipes/users/4173018/">David Mertz</a> (<a href="/recipes/tags/annotations/">annotations</a>, <a href="/recipes/tags/check/">check</a>, <a href="/recipes/tags/decorator/">decorator</a>, <a href="/recipes/tags/python3/">python3</a>, <a href="/recipes/tags/type/">type</a>, <a href="/recipes/tags/typecheck/">typecheck</a>). Revision 5. </p> <p>Some other recipes have been suggested to allow type checking by various means. Some of these require the use of type specification in a decorator itself. Others try to be much more elaborate in processing a large variety of annotations (but hence require much more and more convoluted code).</p> <p>The recipe provided below is very short, and simply provides actual <strong>type</strong> checking of arguments and return values. It utilizes an unadorned decorator, rather than manufacture one that is parameterized by types or other arguments.</p>
