A 64-bit signed integer.
Decimal and hexadecimal literals are supported, the latter with a `0x` prefix.

![integer-literal grammar](/reference/vcl/img/integer-literal.svg)

For example:

```vcl
set resp.status = 200;
set var.i = 0x5a5a;
```

The INTEGER type can represent one more value on the negative side than on the
positive side.
Being 64-bit, its range is −(2<sup>63</sup>) to 2<sup>63</sup> − 1 inclusive.
That is, the minimum and maximum values are -9223372036854775808 and
9223372036854775807 respectively,
or -0x8000000000000000 and 0x7FFFFFFFFFFFFFFF in hexadecimal.

A leading `-` for negative numbers is considered part of the
literal syntax, rather than as a separate unary operator.
Therefore a literal may be given with the maximum negative value:

```vcl
declare local var.min INTEGER;
declare local var.max INTEGER;

set var.min = -9223372036854775808;
set var.max =  9223372036854775807;

set var.min = -0x8000000000000000;
set var.max =  0x7FFFFFFFFFFFFFFF;
```
