If no value is given (i.e. the array is empty) the process returns `true`.\n\nBy default, all no-data values are ignored so that the process returns `true` if all values are no-data or true, and `false` otherwise. Setting the `ignore_nodata` flag to `false` takes no-data values into account and the array values are reduced pairwise according to the following truth table:\n\n```\n        || no-data | false | true\n------- || ------- | ----- | -------\nno-data || no-data | false | no-data\nfalse   || false   | false | false\ntrue    || no-data | false | true\n```\n\n**Remark:** The process evaluates all values in an arbitrary order and stops once the outcome is unambiguous, i.e. when either a `false` value is encountered, or when all values have been taken into account.",
