COUNT
Counts the numbers in the list of arguments. Text entries are ignored.
Syntax:
COUNT(value1; value2; ... value30)
value1 to value30 are up to 30 values or ranges representing the values to be counted.
Example:
COUNT(2; 4; 6; "eight")
- returns 3, because 2, 4 and 6 are numbers ("eight" is text).
COUNT(B1:B3)
- where cells B1, B2, B3 contain 1.1, 2.2, and apple returns 2.
