$section Machine Epsilon For AD Types$$

$head Deprecated 2012-06-17$$
$index deprecated, epsilon$$
This routine has bee deprecated.
You should use the $cref/numeric_limits/limits/$$ $code epsilon$$ instead.

$head Syntax$$
$icode%eps% = epsilon<%Float%>()%$$

$head Purpose$$
Obtain the value of machine epsilon corresponding
to the type $icode%Float%$$.

$head Float$$
this type can either be $codei%AD<%Base%>%$$,
or it can be $icode Base$$ for any $codei%AD<%Base%>%$$ type.

$head eps$$
The result $icode eps$$ has prototype
$codei%
	%Float% eps
%$$
