Quantities are representations of small or large numbers using a compact,
whole-number notation with SI suffixes. Fractional numbers are represented
using milli units, while large numbers can be represented using kilo,
mega, or giga units.
For instance, the number `1.5` is represented as `1500m`, while the number `1000`
can be represented as `1k`, and `1000000` as `1M`. You can also specify
binary-notation suffixes; the number 2048 can be written as `2Ki`.
The accepted decimal (power-of-10) units are `m` (milli), `k` (kilo,
intentionally lowercase), `M` (mega), `G` (giga), `T` (terra), `P` (peta),
`E` (exa).
The accepted binary (power-of-2) units are `Ki` (kibi), `Mi` (mebi), `Gi` (gibi),
`Ti` (tebi), `Pi` (pebi), `Ei` (exbi).
