class="inline">STRING</code></h2> <p>Every class has the <code lang="eiffel" class="inline">out</code> method that can be used to get a text version of the object. For a lot of classes, this method returns internal information that is not really useful for the end user. But for every <code lang="eiffel" class="inline">NUMERIC</code> class, the <code lang="eiffel" class="inline">out</code> method returns a text representation of the number that the <code lang="eiffel" class="inline">NUMERIC</code> object represents. </p> <p><code> print_integer (a_integer: INTEGER) -- Print the value of `a_integer`. do print (a_integer.out + "%N") end</code> </p> <p>Note that for more advanced conversion, you can also use a conversion class like <code lang="eiffel" class="inline">FORMAT_DOUBLE</code>. </p> <a id="%3Ccode_lang=%22eiffel%22%3ESTRING%3C/code%3E_to_%3Ccode_lang=%22eiffel%22%3ENUMERIC%3C/code%3E"></a><h2><code lang="eiffel" class="inline">STRING</code> to <code lang="eiffel" class="inline">NUMERIC</code></h2> <p>The reverse conversion is available for all standard numeric types (<code lang="eiffel" class="inline">INTEGER_8</code>, <code lang="eiffel" class="inline">INTEGER_16</code>, etc.) using the features <code lang="eiffel" class="inline">to_integer_8</code>, <code lang="eiffel" class="inline">to_integer_16</code>, etc. of class <code lang="eiffel" class="inline">STRING</code>. The string should contain a valid string representation of the corresponding numeric value. This can be checked by calling <code lang="eiffel" class="inline">is_integer_8</code>, <code lang="eiffel" class="inline">is_integer_16</code>, etc. before calling the conversion functions. </p> </div> <div class="wdocs-nav"><div class="wdocs-nav-section">Back to <a href="/doc/eiffel/Mini_How-tos" class="wdocs-folder">Mini How-tos</a></div><div class="wdocs-uuid"><a href="/doc/uuid/B74D374E-895C-4F22-B95F-656BD78ECD03">Permanent link</a></div> </div> <div class="wdocs-cache-info">cached: 02/25/2025 8:45:30.000 PM</div></div> <div class="roc-comments-ext"> <div id="remark42"></div> <script> var remark_config = { site_id: 'eiffel-org-comments', url: 'https://www.eiffel.org/doc/uuid/B74D374E-895C-4F22-B95F-656BD78ECD03', // Replace PAGE_URL with your page's canonical URL variable max_shown_comments: 25, // optional param; if it isn't defined default value (15) will be used theme: 'dark', // optional param; if it isn't defined default value ('light') will be used }; (function() { var d = document, s = d.createElement('script'); s.src = 'https://remark.eiffel.org/web/embed.js'; // prepends this address with domain where remark42 is placed (d.head || d.body).appendChild(s); })(); </script> </div> </div> </div> </section> </main>  <footer id="footer"> <div class="container"> <nav class="footer-nav"> <ul class="grid-5 has-gutter"> <li class="one-sixth"><a href="https://www.eiffel.org/welcome">Welcome</a> <ul> <li><a href="https://www.eiffel.org/purpose">Purpose</a></li> <li><a href="https://www.eiffel.org/news">News</a></li> <li><a href="https://www.eiffel.org/updates">Updates</a></li> <li><a href="https://www.eiffel.org/forum">Forum</a></li> <li><a href="https://www.eiffel.org/community">Community</a></li> <li><a href="https://www.eiffel.org/contact">Contact</a></li> <li> <a href="/account/roc-login?destination=doc%2Feiffel%2FGetting_a_STRING_from_a_NUMERIC_object">Sign in</a> </li> </ul> </li> <li class="one-sixth"><a href="https://www.eiffel.org/documentation">Documentation</a> <ul> <li><a href="https://www.eiffel.org/doc/eiffel">Eiffel</a></li> <li><a href="https://www.eiffel.org/doc/eiffelstudio">EiffelStudio</a></li> <li><a href="https://www.eiffel.org/doc/solutions">Solutions</a></li> <li><a href="https://www.eiffel.org/doc/glossary">Glossary</a></li> <li><a href="https://www.eiffel.org/doc/faqs">FAQs</a></li> <li><a href="https://www.eiffel.org/contribute">Contribute</a></li> </ul> </li> <li class="one-sixth"><a href="https://www.eiffel.org/resources">Resources</a> <ul> <li><a href="https://www.eiffel.org/resources/libraries">Libraries</a></li> <li><a href="https://www.eiffel.org/resources/tools">Tools</a></li> <li><a href="https://www.eiffel.org/resources/wish_list">Wish list</a></li> <li><a href="https://www.eiffel.org/resources/videos">Videos</a></li> <li><a href="https://www.eiffel.org/resources/follow_us">Follow us</a></li> </ul> </li> <li class=""> <div class="btn-holder"> <a class="btn btn-download" href="https://www.eiffel.org/downloads">Download Now</a> <a class="btn btn-tryonline" href="https://www.eiffel.org/try_eiffel">Try Eiffel Online</a> <a class="btn btn-contribute" href="https://www.eiffel.org/contribute">Contribute</a> <a class="btn btn-account" href="/account/roc-login?destination=doc%2Feiffel%2FGetting_a_STRING_from_a_NUMERIC_object">Sign in</a> </div> </li> <li class="one-sixth"> <ul class="social-networks"> <li><a class="facebook" target="_blank" href="https://www.facebook.com/pages/Eiffel-Programming-Language/235981463124887">Facebook</a></li> <li><a class="youtube" target="_blank" href="http://www.youtube.com/user/EiffelLanguage">You Tube</a></li> <li><a class="twitter" target="_blank" href="https://twitter.com/Eiffel_Language">Twitter</a></li> </ul> </li> </ul> </nav>  <div style="float: right">Built with the Eiffel ROC CMS and the <a href="http://www.eiffelweb.org">EiffelWeb framework</a>.</div> </div> </footer> <script src="/theme/responsive-eiffel-org/js/wdownloads.js"></script> <script src="/theme/responsive-eiffel-org/js/home.js"></script> <link href="/theme/responsive-eiffel-org/js/google-code-prettify-eiffel/styles/lang-eiffel.css" type="text/css" rel="stylesheet" /> <script src="https://cdn.jsdelivr.net/gh/google/code-prettify@master/loader/run_prettify.js"></script> <script src="/theme/responsive-eiffel-org/js/google-code-prettify-eiffel/src/lang-eiffel.js"></script> <script src="https://www.google.com/recaptcha/api.js" async defer></script> </div> </body> </html>
