While trying hard to be non technical, % is not a unit (dimension) but a multiplier. In km, m is the unit (meter) and k is the multiplier (1000). In "%" there is no unit and the multiplier is .01. My snippy comment means that many people seeing "10" would ask "10 what?". A dimensionless value is disturbing and that's why people like to keep something with %. So, why remove what doesn't hurt indeed, is self-describing and that everybody understands? It ain't broke ! ;-)
For technical people, a 10% slope is .10 and a school mark is between 0 and 1. But I see that several of us are writing the same thing at the same time ;-) I just found a more interesting subject ;-) Cheers, André. > > Mike > > > On Mon, Aug 12, 2013 at 11:37 AM, Ronnie Soak > <chaoschaos0...@googlemail.com <mailto:chaoschaos0...@googlemail.com>> > wrote: > > > > 2013/8/12 André Pirard <a.pirard.pa...@gmail.com > <mailto:a.pirard.pa...@gmail.com>> > > Imagine seeing on a shop poster "10 OFF" or "0.1 OFF" and > you've got the answer to THAT point. > > > Can I extract from your snippy comment, that in your opinion we > should omit the % sign because one can clearly distinguish between > a pure ratio and a percent-scaled ratio? > What about the distinction between the percent-value and a value > in degrees? > > > Regards, > Chaos > > _______________________________________________ > Tagging mailing list > Tagging@openstreetmap.org <mailto:Tagging@openstreetmap.org> > http://lists.openstreetmap.org/listinfo/tagging > > > > > _______________________________________________ > Tagging mailing list > Tagging@openstreetmap.org > http://lists.openstreetmap.org/listinfo/tagging
