I've been overtaken :) Isn't that an active mailing list ? On 16 juil. 2014, at 00:53, Camille Teruel <camille.teruel@gmail.com> wrote:
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

Hi,
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
