Documentation/How Tos/Calc: COUNT function
From Apache OpenOffice Wiki
Counts the numbers in the list of arguments, ignoring text entries.
COUNT(value1; value2; ... value30)
value1 to value30 are up to 30 values or ranges representing the values to be counted.
COUNT(2; 4; 6; "eight")
- returns 3, because 2, 4 and 6 are numbers ("eight" is text).
- where cells B1, B2, B3 contain 1.1, 2.2, and apple returns 2.
- The draft ODFF standard requires error values to be ignored, not propagated as in Calc. See issue 51068.
- The draft ODFF standard requires that text representations of numbers are NOT counted. Calc complies for text representations of numbers in cells, in contrast to Excel. However, COUNT(4; "4") will return 2, as inline strings are converted to numbers if possible. This is described in the ODFF standard (28Dec07) in section 2.2 page 35.
