exp2(string|int|float $value) : string

This helper wraps the ArangoDB AQL function EXP2(value) which returns 2 raised to the power of the given value. This is useful for binary operations and exponential growth calculations.

Example AQL usage:

EXP2(0)                       // returns 1
EXP2(1)                       // returns 2
EXP2(2)                       // returns 4
EXP2(3)                       // returns 8
EXP2(-1)                      // returns 0.5
Parameters
$value : string|int|float

The exponent value.
