This arithmetic operator returns the opposite of its argument. It has been overloaded to handle constrained expressions appropriately. The domain of the resulting expression is computed from the domain of the original expression as you would expect.

These operators create a composite IloEvaluator<IloObject> instance. The semantics of the new evaluator are the subtraction of the values of the component evaluators. The first function combines two evaluators, subtracting the value returned by the first by the value returned by the second. The next two functions combine an IloNum value with an evaluator. In the first of these functions, the IloNum value is subtracted from the value returned by the evaluator, while in the second of these functions those roles are reversed. The last function returns the opposite of an evaluator.

This operator creates and returns a function equal to the difference between functions f1 and f2. The argument functions f1 and f2 must be defined on the same interval. The resulting function is defined on the same interval as the arguments. See also: IloNumToNumStepFunction.

This arithmetic operator subtracts its second argument from its first. It has been overloaded to handle constrained expressions appropriately. The domain of the resulting expression is computed from the domains of the combined expressions as you would expect.

This overloaded C++ operator returns an expression equal to the difference of its arguments. Its arguments may be numeric values, numeric variables, or other expressions.
