Expand description

Equivalent to C’s `signed long long` (`long long`) type.

This type will almost always be `i64`, but may differ on some systems. The C standard technically only requires that this type be a signed integer that is at least 64 bits and at least the size of a `long`, although in practice, no system would have a `long long` that is not an `i64`, as most systems do not have a standardised `i128` type.
