Where 190 fits
Why 190 is special
Its rivalry with BMW's M3 drove German touring car racing through the 1980s, and the road cars sold on the strength of a competition the manufacturers were funding largely to sell road cars.
Same number, different meanings
How 190 is understood across different contexts — never implying one meaning because of another.

- Technology & computing
CWE-190 is integer overflow or wraparound. A size calculation that wraps produces an allocation smaller than intended, which is how integer defects become memory corruption.
- Sport
The 190E's motorsport programme existed substantially to support road car sales, and the resulting rivalry with BMW shaped touring car racing for a decade. The commercial logic is explicit rather than incidental.

Roman numerals
C X C
CXC uses the subtractive pair XC: ten before a hundred — a hundred minus ten.
Binary
1 0 1 1 1 1 1 0
1 × 128 + 0 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 1 × 4 + 1 × 2 + 0 × 1 = 190

b × 16 + e × 1 = 190
Read as powers of two: 128 + 32 + 16 + 8 + 4 + 2 = 190.
In historical numeral systems
Egyptian
1 coil of rope, 9 hobbles
1 × 100 + 9 × 10 = 190. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 1 corner wedge (units place)
3 × 60 + 10 = 190. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then koppa, marked as a numeral
rho-koppa + keraia
rho + koppa written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then tsadi
qof-tsadi
qof (100) + tsadi (90) = 190, written in descending order.
Maya
1 bar + 4 dots (upper, twenties place) over 2 bars (lower, units place)
9 × 20 + 10 = 190. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

Common questions
Is 190 a prime number?
No, 190 is not prime.
What are the factors of 190?
The factors of 190 are 1, 2, 5, 10, 19, 38, 95, 190.
What is 190 in Roman numerals?
190 in Roman numerals is CXC. XC is subtractive: ten before a hundred — a hundred minus ten. Written additively it would be CLXXXX, which Roman inscriptions used freely — the strict subtractive form is a later convention.
