A reference to an empty cell is interpreted as the numeric value 0.
A matching expression can be:
A number or logical value. A matching cell content equals the number or logical value.
A value beginning with a comparator (<, <=, =, >, >=, <>).
For =, if the value is empty it matches empty cells.
For <>, if the value is empty it matches non-empty cells.
For <>, if the value is not empty it matches any cell content except the value, including empty cells.
Note: "=0" does not match empty cells.
For = and <>, if the value is not empty and can not be interpreted as a number type or one of its subtypes and the property Search criteria = and <> must apply to whole cells is checked, comparison is against the entire cell contents, if unchecked, comparison is against any subpart of the field that matches the criteria. For = and <>, if the value is not empty and can not be interpreted as a Number type or one of its subtypes applies.
Other Text value. If the property Search criteria = and <> must apply to whole cells is true, the comparison is against the entire cell contents, if false, comparison is against any subpart of the field that matches the criteria. The expression can contain text, numbers, regular expressions or wildcards (if enabled in calculation options).
