我正在處理javascript。我希望它總計在兩位小數。所以如果我加: 25.321 + 300.693 = 326.014將結果舍入到小數點後兩位
我想要的總和爲:326.01。這裏是我的代碼:
function civ(){
civ1=Number(document.addition.scc.value);
civ2=Number(document.addition.ccc.value);
civ3=Number(document.addition.ncc.value);
civ4=Number(document.addition.vch.value);
civ5=Number(document.addition.mch.value);
civ6=Number(document.addition.nlch.value);
civ7=Number(document.addition.slch.value);
valNum1=civ1+civ2+civ3+civ4+civ5+civ6+civ7;
document.addition.civ123.value=valNum1;
}
我也試試這個:
function civ(){
civ1=Number(document.addition.scc.value);
civ2=Number(document.addition.ccc.value);
civ3=Number(document.addition.ncc.value);
civ4=Number(document.addition.vch.value);
civ5=Number(document.addition.mch.value);
civ6=Number(document.addition.nlch.value);
civ7=Number(document.addition.slch.value);
valNum1=Math.round(civ1+civ2+civ3+civ4+civ5+civ6+civ7*100)/100;
document.addition.civ123.value=valNum1;
}
但結果不正確。我再次添加2個數字(128.65 + 0)= 1.29或1.28(我忘了)。感謝那些願意幫助的人。
操作
嘿Ujjwal,謝謝! :) – catsgirl008 2011-03-24 06:42:51
