I would suggest something like that:
--- a/doc/src/sgml/config.sgml
+++ b/doc/src/sgml/config.sgml
@@ -2050,7 +2050,8 @@ include_dir 'conf.d'

- The default is 2.0.
+ The default is 2.0. The value can range from <literal>2.0</literal>
+ to <literal>10.0</literal>
This parameter can only be set in the
<filename>postgresql.conf</filename>
