[Tagging] Mapping larger Mini-roundabouts

Mini roundabouts are normally too small to be anything but round. 

I realise that we would use decimal s rather than fractions. But in most cases a guestimate of diameter in metres will do. Most will be either 1, 2 or 3 metres, using radius there will be a lot that are radius of 0.5m.

And I refuse to try measuring the ones on the A53 with a tape measure
;)

You and I both seem to understand it. Let's not underestimate the ability of

A diameter could have a fractional part, although we would use a decimal 
point.


Best wishes,
