<noinclude>
Use this template to extract the first page number from a page-page string. For instance, if (e.g. <code><nowiki>pages="23-45")</nowiki></code>, the template will return 23. If <code><nowiki>pages="234"</nowiki></code>, the template will return 234. If an empty string is passed as a value, an empty string is returned. E
'''NOTE:''' As any "printing" template, it doesn't store any values anywhere, but merely prints them on the page.
