[expr if ($f3 > 0, $f1 + $f2, $f1 - $f2)] will give you only one outlet. You can even nest if statements: [expr if ($f3 > 0, $f1 + $f2, if ($f3 < 0, $f1 - $f2, 0))] -Jonathan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] [expr] for "if, then, else"?
You don't need to declare the variables... it is just: [expr if ($f3 > 0, $f1 + $f2, 0); if ($f3 < 0, $f1 - $f2, 0)] but you will have 2 outlets (one for each "if"), and not an "else" for the same outlet in fact, it would be nice to have an "else" on Yadegari's externals...
