   * ''if(col(B) >= 0, col(B), NaN)'' --- returns only positive values from column B. Negative values are replaced with ''NaN'' value (empty cell). You can use this expression to filter negative values if you do not want to use them in future calculations. Note that "//Not-a-Number returned at row #//" warning can be shown for such expression.   * ''if(col(B) >= 0, col(B), NaN)'' --- returns only positive values from column B.
