You should use the :ref:`numeric_limits-name` ``epsilon`` instead. Syntax ****** *eps* = ``epsilon`` < *Float* >() Purpose ******* Obtain the value of machine epsilon corresponding to the type *Float* . Float ***** this type can either be ``AD`` < *Base* > , or it can be *Base* for any ``AD`` < *Base* > type. eps *** The result *eps* has prototype *Float* ``eps`` {xrst_end epsilon}
