  • $\begingroup$ Would this question help you? $\endgroup$ Commented Feb 18, 2019 at 17:12
  • $\begingroup$ Whether this is possible depends on additional context, such as whether you have an upper bound on $x$ and whether you already have an objective function. See "Cast to boolean" at cs.stackexchange.com/q/12102/755. Is your question answered by any of those? If not, can you edit your question to provide additional context and explain why those solutions are not applicable here? $\endgroup$ Commented Feb 18, 2019 at 20:17
  • $\begingroup$ @Apass.Jack Actually my question is based on the one you linked. I tried the most voted solution, but apparently C cannot be 0. $\endgroup$ Commented Feb 19, 2019 at 10:06
  • $\begingroup$ @D.W. I have a lower (0) and upper bound for x. The "Cast to boolean (version 1)" solution in the page you linked seems to work perfectly fine. Thanks. $\endgroup$ Commented Feb 19, 2019 at 10:06
