问题 I have a problem in showing the decimals on the average. It keeps showing .00 or .1. I tried to put it in double, but I still get the same results.Also, I want to include the first integer that I input to the sum, but I have no idea how.Please help: import java.io.*; import java.util.*; public class WhileSentinelSum { static final int SENTINEL= -999; public static void main(String[] args) { // Keyboard Initialization Scanner kbin = new Scanner(System.in); //Variable Initialization and

问题 This is a "weighted average" formula where Q14:Q21 contains the "weights"; Column C is the first column of data, and subsequent columns are D:P I can use this formula, and fill right. The data columns will change and the "weight" column remain the same. =SUMPRODUCT(Sheet1!C$14:C$21,Sheet1!$Q$14:$Q$21)/SUM(Sheet1!$Q$14:$Q$21) I would like to change the data to a "table" so as to be able to use structured references. The "weights" column header is Percent , and the data columns are year numbers

问题 just a simple problem here. I have the following array: Array(21) { [0] => Array(7) { ["punti"] => Integer 418 ["vittorie"] => Integer 9 ["podi"] => Integer 18 ["gv"] => Integer 14 ["id_pilota"] => Integer 1 ["team"] => String(15) "Red Bull Racing" ["naz"] => String(2) "it" } [1] => Array(7) { ["punti"] => Integer 353 ["vittorie"] => Integer 6 ["podi"] => Integer 16 ["gv"] => Integer 3 ["id_pilota"] => Integer 19 ["team"] => String(16) "Scuderia Ferrari" ["naz"] => String(2) "it" } [2] =>

问题 I used the following function I found online and it works perfectly. However, when my user later asked for commas to be included in the numbers, it broke. It only adds the numbers preceding the comma. Here is the function: function sumOfColumns(tableID, columnIndex, hasHeader) { var tot = 0; $("#" + tableID + " tr" + (hasHeader ? ":gt(0)" : "")) .children("td:nth-child(" + columnIndex + ")") .each(function() { tot += parseInt($(this).html()); }); Do I need to stop the 'parseInt' piece? 回答1: I

问题 I am doing a ledger for accounting purposes. I have it set up like a checkbook registry. It has 4 columns: Date, Description, Amount and Balance. The formula set up in the last column (Balance) is set up to add the number in the "Amount" column to the balance in the last line entry. The formula is copied down the page in the last column. What I would like to do, is only have a number in that column if there is an entry on that line. Here is my question: Is there a way to hide the number in

问题 I want to calculate the sum of the orders based on the flag. Sample table: +--------------+---------------+---------------+ | Order | Flag | Amount | +--------------+---------------+---------------+ | Order1 | Yes | 500 | | Order1 | Yes | 325 | | Order2 | Yes | 799 | | Order2 | No | 550 | | Order2 | Yes | 675 | | Order3 | No | 800 | +--------------+---------------+---------------+ I want to create 2 new columns. One column is the total amount of order and another one is the total amount of

问题 i've just started java programming and was wondering on how to approach or solve this problem i'm faced with. I have to write a program that asks a user for a number and continually sums the numbers inputted and print the result. This program stops when the user enters "END" I just can't seem to think of a solution to this problem, any help or guidance throughout this problem would be much appreciated and would really help me understand problems like this. This is the best i could do public

问题 I am trying to sum multiple rows together based on a keyword that is part of the index - but it is not the entire index. For example, the index could look like Count 1234_Banana_Green 43 4321_Banana_Yellow 34 2244_Banana_Brown 23 12345_Apple_Red 45 I would like to sum all of the rows that have the same "keyword" within them and create a total "banana" row. Is there a way to do this without searching for the keyword "banana"? For my purposes, this keyword changes every time and I would like to
