ansible.builtin.nan test – is this not a number (NaN)

Note

This test plugin is part of ansible-core and included in all Ansible installations. In most cases, you can use the short plugin name nan. However, we recommend you use the Fully Qualified Collection Name (FQCN) ansible.builtin.nan for easy linking to the plugin documentation and to avoid conflicting with other collections that may have the same test plugin name.
