I've been overtaken :) Isn't that an active mailing list ?

Hi Max, Pharo doesn't have syntax for prefix operator like "-". The parser does accepts a "-" before literal numbers but it's not possible for arbitrary expressions.
However you have the message #negated .
negatedWidth ^ self width negated
Cheers, Camille

I am using latest Pharo 3.0 + vm.
I have a method width with width
^ 115 * self ratio. in my understanding it returns a Number.
When I try to create a method negatedWidth
^ - (self width).
the UI tells me that only Numbers may be negated. I am not able to save the method. Am I on a wrong path or should that work and if how can I avoid the UI error message?
Regards
Max
