Where 5500 fits
Why 5500 is special
That is close to the Sun's surface temperature, and it is kept liquid in the outer core by pressure. The convection of that liquid iron generates the magnetic field that deflects solar wind.

1 × 4,096 + 5 × 256 + 7 × 16 + c × 1 = 5,500
Read as powers of two: 4,096 + 1,024 + 256 + 64 + 32 + 16 + 8 + 4 = 5,500.

5 × 1,000 + 5 × 100 = 5,500. 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.

Science
Earth's core approaches the Sun's surface temperature. The circulation of liquid iron there generates the magnetic field without which the atmosphere would be stripped by solar wind.
