INTEGER

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

For example:

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 −(2⁶³) to 2⁶³ − 1 inclusive. That is, the minimum and maximum values are -9223372036854775808 and 9223372036854775807 respectively.

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:

set var.i =  9223372036854775807;
set var.i = -9223372036854775808;
