Deprecated 2012-06-17
This routine has been deprecated. You should use the numeric_limits 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
