Comment (by dd32):

 > You can also use floatval($wp_version) to get the major version number.

 That's what we do in Core, but you have to be aware that some non-en
 locale's don't use . as the decimal seperator, and so you end up with 3,2
 See trunk's code here: [http://core.trac.wordpress.org/browser/trunk/wp-
 admin/admin-header.php#L85 admin-header.php#L85]

 Ideally though, you shouldn't need to do version compares if at all
 possible.. Instead you should be feature testing, For example: [19580]
 {{{
 +       $screen = get_current_screen();
 +
 +       if ( method_exists( $screen, 'add_help_tab' ) ) {
 +               // WordPress 3.3
 +               $screen->add_help_tab( array(
 +                       'title' => __( 'Overview', 'twentyeleven' ),
 +                       'id' => 'theme-options-help',
 +                       'content' => $help,
 +                       )
 +               );
 +
 +               $screen->set_help_sidebar( $sidebar );
 +       } else {
 +               // WordPress 3.2
 +               add_contextual_help( $screen, $help . $sidebar );
 +       }
 }}}
