It's not just specific to 1/0 error, but any type of error or warning I want it to ignore it and skip to the next value; with the final output being a list of valid answers according to expr. > > Is there a way to do that? Thanks! Hi Mike There is one sugestion: Table[1/i, {i, -3, 2}] // Quiet // DeleteCases[#, ComplexInfinity] & Quiet removes the error msg DeleteCases remove the unwanted complex Best Regards Murta
