こんにちは、私はこの JavaScript テーブルを持っています。これに小数点 (2) を追加する方法を誰かが説明するのを手伝ってくれるかどうか疑問に思っていました。どんな助けでも大歓迎です。

//Total Expenditure - Total
document.write ('<tr align="center"><td>' + row14col1var + '<\/td><td>' + row14col2var + '<\/td><td>' + row14col3var + '<\/td><td>' + row14col4var + '<\/td><td>' + row14col5var + '<\/td><td>' + row14col6var + '<\/td><td>' + row14col7var + '<\/td><td>' + row14col8var +'<\/td><td>' + row14col9var + '<\/td><td>' + row14col10var + '<\/td><td>' + row14col11var + '<\/td><td>' + row14col12var + '<\/td><td>' + row14col13var + '<\/td><td>' + row14col14var +'<\/td><\/tr>');

var row14col1var = '<b>Total Expenditure</b>';

var row14col2var = ( Number(row4col2var) + Number(row5col2var) + Number(row6col2var)+   Number(row7col2var)+ Number(row10col2var)+ Number(row11col2var)+ Number(row13col2var));

var row14col3var = ( Number(row4col3var) + Number(row5col3var) + Number(row6col3var) + Number(row7col3var)+ Number(row10col3var)+ Number(row11col3var)+ Number(row13col3var));

var row14col6var = ( Number(row4col6var) + Number(row5col6var) + Number(row6col6var)+ Number(row7col6var)+ Number(row10col6var)+ Number(row11col6var)+ Number(row13col6var));

var row14col7var = ( Number(row4col7var) + Number(row5col7var) + Number(row6col7var)+ Number(row7col7var)+ Number(row10col7var)+ Number(row11col7var)+ Number(row13col7var));

var row14col8var = ( Number(row4col8var) + Number(row5col8var) + Number(row6col8var)+ Number(row7col8var)+ Number(row10col8var)+ Number(row11col8var)+ Number(row13col8var));

var row14col9var = ( Number(row4col9var) + Number(row5col9var) + Number(row6col9var)+ Number(row7col9var)+ Number(row10col9var)+ Number(row11col9var)+ Number(row13col9var));

var row14col10var = ( Number(row4col10var) + Number(row5col10var) + Number(row6col10var)+ Number(row7col10var)+ Number(row10col10var)+ Number(row11col10var)+ Number(row13col10var));

var row14col11var = ( Number(row4col11var) + Number(row5col11var) + Number(row6col11var)+ Number(row7col11var)+ Number(row10col11var)+ Number(row11col11var)+ Number(row13col11var));

私はあなたのコードの多くの設計上の問題を無視して、あなたの質問に答えます。各数値の下 2 桁の前に小数点を追加する場合は、次のようにしますtoFixed(2)。

var row14col2var = (Number(row4col2var) + ... snip ...).toFixed(2);
