The condition Number Compare checks if a specific metadata field contains a number that is less, less or equal, equal, greater, greater or equal to a specific value e.g. Check weather the resolution is greater or equal 300 dpi to meet the website requirements before pushing content to the website (handled via separate integration).
A field value of 20 in this condition mean value:20 and mode: equals. The Business Rule triggers this very moment e.g. check if amount sold is 100 to then e.g. apply discount flag. Number compare works for Geo Points but requires two conditions (number compare for lat; number compare for lon).
