Use this template to extract the first page number from a page-page string. For instance, if pages="23-45", the template will return 23. If pages="234", the template will return 234. If an empty string is passed as a value, an empty string is returned.

NOTE: As any "printing" template, it doesn't store any values anywhere, but merely prints them on the page.

Parameters:

  • |pages= - pages in the "xx-yy" format. E.g. "23-145", "1-34", "vi-ix", etc.
