evaluate
in interface Function
args
- the evaluated function arguments. Empty values are represented with
BlankEval
or MissingArgEval
, never null
.srcRow
- row index of the cell containing the formula under evaluationsrcCol
- column index of the cell containing the formula under evaluationErrorEval
, never null
.
Note - Excel uses the error code #NUM! instead of IEEE NaN, so when
numeric functions evaluate to Double.NaN
be sure to translate the result to ErrorEval.NUM_ERROR
