> Calcite currently supports the {{LN}} and {{LOG10}} function. BigQuery offers the {{LOG}} function which allows for the base of the logarithm to be specified as a second argument. If the second argument is not provided, the base is defaulted to e (making it identical to the {{LN}} function. 
> Example: {{LOG(64, 10)}} would return {{2}}.
> Example 2: {{LOG(10)}} would return the same as {{LN(10)}}.
