rand() : string

This helper wraps the ArangoDB AQL function RAND() which returns a pseudo-random number between 0 (inclusive) and 1 (exclusive). The algorithm for random number generation should be treated as opaque.

Example AQL usage:

RAND()                        // returns a random number like 0.123456789
RAND() * 100                  // returns a random number between 0 and 100
FLOOR(RAND() * 6) + 1         // returns a random integer between 1 and 6
