the problem in which the variable belongs
the lower bound in the domain
the upper bound in the domain
unbounded domain (-inf, +inf)
the symbol of the variable (default is ANONYMOUS)
true if the variable is a binary integer variable (e.g. 0-1).
true if the variable is integer, false otherwise.
true if the variable is unbounded, false otherwise.

the value of the variable (integer rounded if the variable is integer).
Mathematical programming unbounded variable in the problem. The domain is defined (0, +inf) if the variable is unbounded or (-inf, +inf) otherwise.
