The Unsigned Range
Captions available
The idea
An unsigned integer is a non-negative integer, and n bits present exactly 2 to the n values — the range running from zero up to 2 to the n, minus one.
In practice
Three bits on a scoreboard cover eight scores, zero through seven, and not one more.
Where people slip
The ceiling is arithmetic, not policy.
