The - operator has been tricky because sometimes acts as as binary (the ordinary subtraction) and other times is unary (inverting the sign of the number that is next to it), I submitted a patch and hopefully no more issues will arise. If any other input gives wrong results let me know, for sure we could use some more testing since the feature is fairly new. -- You are receiving this mail because: You are watching all bug changes.
