I think what you're looking for is a string eval, which would be something like this:
if (eval "\$consumption $operator")

But I wouldn't recommend you do that. It means any errors in $operator will be runtime instead of compile-time errors, and that code will be re-compiled every time through your loop, which is bad for performance.

Instead, consider customizing your condition with a small sub, something like:

sub process_match { my($consumption)=@_; return $consumption > 98.0; } if (process_match($consumption)) { do something; }
This gives you the same flexibility without any of the downsides of string eval.

Good luck!

Update: $consumption should be escaped in eval. Thanks, ikegami!
