Real-valued discrete design variables

Description::
A design variable whose values come from a specified set of admissible
reals.  See :ref:`variables:usage` for tips on specifying discrete set
variables.

Topics::
discrete_variables, design_variables
Examples::
Two continuous, restricted variables whose values will be selected
from the following sets during the search for an optimal design. :math:`y1
\in \{0.25,1.25, 2.25, 3.25, 4.25\}` , :math:`y2 \in \{0,5\}`
