log10(string|int|float $value) : string

This helper wraps the ArangoDB AQL function LOG10(value) which returns the base-10 logarithm (common logarithm) of a value. The value must be greater than 0, otherwise it returns null.

Example AQL usage:

LOG10(1)                      // returns 0
LOG10(10)                     // returns 1
LOG10(100)                    // returns 2
LOG10(1000)                   // returns 3
LOG10(0)                      // returns null (invalid input)
Parameters
$value : string|int|float

The input value (must be greater than 0).
