?ExprX #= ?ExprY
ExprX is equal to ExprY (with integrality constraints).
- ExprX
- Integer arithmetic expression
- ExprY
- Integer arithmetic expression
Description
   Constrains ExprX and ExprY to be equal.  Also constrains all variables
   appearing in ExprX and ExprY to be integral and checks that all constants
   are integers.
   Note that if all variables and constants appearing in this constraint
   are already integral, then the constraint is equivalent to
   ic:(ExprX =:= ExprY).
