Why 4180 is special

It was written in 2005 to describe a format already thirty years old, and it is informational rather than binding — which is why CSV files still disagree with each other.

In historical numeral systems

Egyptian

4 lotuses, 1 coil of rope, 8 hobbles

4 × 1,000 + 1 × 100 + 8 × 10 = 4,180. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
