Result of the expression is interpreted as a boolean. Values above zero are regarded "true", values below or equal zero are regarded "false". When "incremental alarm" is specified, Meteobridge compares new value with former value and does trigger an alarm, when new value is bigger then the one that has triggered an alarm before.
