add_menu_page supports decimal positions

When adding top level menu pages to WordPress admin (using add_menu_page) more often or not you’ll end up conflicting with other plugins. When two plugins share the same menu position, one is not shown:

WARNING: if 2 menu items use the same position attribute, one of the items may be overwritten so that only one item displays!

Since there are a limited number of integer positions in the menu this could be a problem, however, handily WordPress actually supports decimal positions. In this example I’m using ‘55.5’ instead of 55. This should reduce the risk of conflict significantly:

$main_page = add_menu_page(__('WooCommerce', 'woocommerce'), __('WooCommerce', 'woocommerce'), 'manage_woocommerce', 'woocommerce' , 'woocommerce_settings_page', null, '55.5' );

Note that the codex and the source state that integers should be used, even though the decimals do work. Kudos to Gary Jones for pointing this trick out.
