Hi Onedaywhen,

No advantage I know of. I merely find the double minus more intuitive
i.e. easier for me to remember. Similarly, why +- when just minus will
do? Answer, using two signs sticks in my mind better!

I'll try to use N in future posts; it'll save me having to explain my
usage.

No problem - it was just that I've seen it used quite frequently
recently, and wondered whether there had been a 'group consensus' that
it was maybe quicker or something.
