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.
