Why 32,767 is special

It is the ceiling that 8-bit and 16-bit systems ran into constantly, and it survives in file formats and protocol fields designed when 16 bits was a sensible width. Anything counting past it in a signed 16-bit field wraps to −32,768, which is why old games cap scores and inventories at oddly specific numbers.

3 × 10,000 + 2 × 1,000 + 7 × 100 + 6 × 10 + 7 × 1 = 32,767. 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.
