+The **Log** function has two parameters:
+==== Number ====
+Allowed Inputs: [[Field|field]] value or a number
+The first parameter of the **Log** function is the value that should result from the base being raised to the resulting power. Either use the query builder or the type a value option to enter a number.
+==== Base ====
+Allowed Inputs: [[Field|field]] value or number
+The second parameter is the number that represents the base of the exponentiation either use the use the [[Query Builder]] to choose a field that contains the value or use type a value to enter a number.  If no value is provided ten will be used.
+===== Output =====
+The output of the **LOG** function is the power to which the base value must be raised to produce the value.
+===== Example =====
+For example LOG(1000) would result in 3 and LOG(19683,3) would result in 9.
