evaluateArray
- Specified by:
evaluateArray
in interfaceArrayFunction
- Parameters:
args
- the evaluated function arguments. Empty values are represented withBlankEval
orMissingArgEval
, nevernull
.srcRowIndex
- row index of the cell containing the formula under evaluationsrcColumnIndex
- column index of the cell containing the formula under evaluation- Returns:
- The evaluated result, possibly an
ErrorEval
, nevernull
. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate toDouble.NaN
be sure to translate the result toErrorEval.NUM_ERROR
