## Number formats

Underscores can be added to numbers for clarity. For example,
`1000000`

can be tricky to read quickly, while
`1_000_000`

can be easier.

Ints can be written in binary, octal, or hexadecimal formats using the
`0b`

, `0o`

, and `0x`

prefixes respectively.

Floats can be written in a scientific notation.
