Variable IloInfinity

This symbolic constant represents the largest double-precision floating-point number on a given platform. It is initialized when you create an instance of IloEnv. In practice, when you use this symbolic constant as an upper bound of a variable in your model, you are effectively stating that the variable is unbounded.

See the IBM ILOG Solver Reference Manual and User's Manual for details about how IBM ILOG Solver treats floating-point calculations in instances of IloSolver in conformity with IEEE 754. In particular, IBM ILOG Solver offers other symbolic constants, such as IlcIntMax or IlcFloatMax that may be more appropriate for your application if you do not intend to state that your variables are effectively unbounded.
