type Compact8 ¶

type Compact8 = uint8

Compact8 is an unsigned 8-bit compact integer encoding with 12 mantissa values per exponent level (instead of the standard power-of-2 split).

For a byte value b, let e = b / 12 and m = b % 12:

b=0:          0                        (zero)
e=0, m>=1:    m << (offset+1)          (subnormal)
e>=1:         (12+m) << (e+offset)     (normalized)

This gives approximately 8.3% relative precision (12 values per octave) and a representable range from 32 to 503316480 with offset 4.
