COUNTNEG function
Description
Count negative numbers function. COUNTNEG(range) counts the number of negative values (< 0) in range.
The argument range can be a list of numbers, cell addresses, cell ranges (such as A1:A10).
Range can also be a matrix. In that case the function returns a matrix with one row and the same number of columns, with each element the COUNTNEG of the corresponding column. If range is a row matrix, it is converted to a column matrix first.
Example
COUNTNEG(A1:A5) returns 3 if the contents of 3 cells in the range A1:A5 are negative values.
