Information class final

A quantity representing digital information — measured in bytes or bits, with both metric (SI) and binary (IEC) prefix variants.

Metric prefixes (kilo, mega, giga, …) use powers of 10 (10³, 10⁶, 10⁹, …). Binary prefixes (kibi, mebi, gibi, …) use powers of 2 (2¹⁰, 2²⁰, 2³⁰, …).

The internal base unit is bytes (B). Bit-based units use a conversion factor of BitsConversionFactor (0.125 = 1/8).
