Detailed Description

The minimum value or size encodable in "Fix" variants of formats.

The only object for which a minimum makes sense is a negative FixNum.

Negative FixNum objects encode their signed integer value in one byte, but they must have the pattern "111" as their three most significant bits. This means all values are negative, and the smallest representable value is 0b11100000.
