match pattern

[Gatet]

I use the "Match Pattern" function to extract a number (the data is temperature), with the following expression: "[0-9]*[\. 0-9][0-9]*" It works, but the minus sign is lost for negative temperatures. How can I solve it?

Thanks

If you use the pattern "[0-9\-][0-9\.][0-9]*[\.0-9][0-9]*" it should work.

Best of luck
