There is this code which used to get price with currency.  Let’s see how to get it.

We can use below helper price to get it.

<?php
use MagentoFrameworkPricingHelperData
protected $priceHelper;
public function __construct(Data $priceHelper)
{
    $this->priceHelper = $priceHelper;
}
public function getFormattedPrice($price)
{
    return $this->priceHelper->currency($price, true, false);
}
?>

Also, we can use directly in phtml file

$this->helper('MagentoFrameworkPricingHelperData')->currency(number_format(50,2),true,false);
