在yii2查詢中使用循環函數

Question

我有一個查詢來從表productbatch得到mrp *率直到2個小數點。 我試過以下查詢Productbatch::find()->select('mrp, rate, round((mrp*rate),2) as rateval')->asArray()->one();

當我僅使用mrp *率時，它給出結果，但小數點後有6或7位數字。請讓我知道我怎樣才能得到結果高達2小數點。

例如

如果我不使用輪和如果MRP = 32和率= 24.64，的mrp*rate結果它給 - 788.47998046875 .. 如果使用圓形如圖所示的代碼它不給出結果。 我想要的是 - 788.48。

Productbatch型號

控制器動作 -

public function actionGetForItemid($prodname , $batchno) 
    { 
     $item = Productbatch::find()->joinWith(['productname0'])->joinWith(['productname0', 'productname0.hsncode'])->select('max(itemid) as itemid, expdate, mrp,rate, productname, batchno, round(rate*mrp,2) as rateval')->where(['productname'=>$prodname])->andWhere(['batchno'=>$batchno])->asArray()->one(); 
     echo Json::encode($item); 
    } 

的Javascript正在調用控制器動作 - 正在填充

<?php 
/* start getting the itemid */ 
$script = <<< JS 
function getItemID(item) { 
    var index = item.attr("id").replace(/[^0-9.]/g, ""); 
    var batch = product = 0; 
    var id = item.attr("id"); 
    var myString = id.split("-").pop(); 

    if (myString == "productname") { 
     fetch = index.concat("-batchno"); 
     product = item.val(); 
     batch = $("#productsales-"+fetch+"").val(); 
    } else { 
     fetch = index.concat("-productname"); 
     batch = item.val(); 
     product = $("#productsales-"+fetch+"").val(); 
    } 
    $.get('index.php?r=invoice/bills/get-for-itemid',{ prodname : product,batchno : batch}, function(data){ 
     alert(data); 
     var data = $.parseJSON(data); 
     var getItemid = data; 
     itemID = "productsales-".concat(index).concat("-itemid"); 
     $("#"+itemID+"").val(getItemid["itemid"]); 
     expDate = "productsales-".concat(index).concat("-expdate"); 
     $("#"+expDate+"").val(getItemid["expdate"]); 
     mRP = "productsales-".concat(index).concat("-mrp"); 
     $("#"+mRP+"").val(getItemid["mrp"]); 
     rATE = "productsales-".concat(index).concat("-rate"); 
     $("#"+rATE+"").val(getItemid["rateval"]); 

    }); 
} 
JS; 
$this->registerJs($script, View::POS_END); 
/* end getting the itemid */ 
?> 

表單域 -

<?= $form->field($modelsProductsales, "[{$i}]rate")->label(false)->textInput(['maxlength' => true,'class' => 'rate','placeholder' => 'Rate']) ?>

要確保你的Productbatch模型具有publica VAR rateval

class Productbatch extends \yii\db\ActiveRecord 
{ 
    public $rateval 
    ... 

，然後你可以使用

$model->rateval; 

指的是你欣賞rateval內容還是做其實你有結果不使用圓形磨mrp*rate 一個簡單的解決方案可以在javascript中回合

Math.round(num * 100)/100 

，並在你的情況

$("#"+rATE+"").val(Math.round(getItemid["rateval"]*100)/100 );
