I'm doing the same thing myself, too. 

I'm using the unary plus not only for documentation, but also for expressing 
intention: It symbolizes that I did not forget a minus sign for that 
specific value. This way a missing unary minus or unary plus makes me 
suspicious that I have done something wrong in my numerical code.
