hello every body ,
i use CplexV9+ Java,
i have some comstraint that have a very big integer number some thing like this
X1+X2+X3+......X120<= 2^120<br />when i implemnet this in cplex i get the following value
-1e+20 
(which is an error) instead of the real value for 2^120 which is = 1.3292279957849158729038070602803e+36
how can i extend the size of my term??
in the other hand when i multiply the value 2^20 by X1, it gives the correct value
1.3292279957849158729038070602803e+36 X1
can you help me please??

Java CPLEX considers values over 1e+20 to be infinity so it just can not handle the sort of constraint you are trying to use.  What are you trying to model with such a constraint?
