How to get total price with discount in Shopify?

Question

I have DataLayer code snippet for Order Status Page Shopify:

    <script>                               
window.dataLayer = window.dataLayer || [];                                            
var shipping_price = '{{shipping_price | money_without_currency }}';
shipping_price  = shipping_price.replace(",", ".");
var total_price = '{{total_price | money_without_currency }}';
total_price  = total_price.replace(",", ".");
var tax_price = '{{tax_price | money_without_currency }}';
tax_price  = tax_price.replace(",", ".");
window.dataLayer.push({
'transactionTotal': total_price,
'transactionShipping': shipping_price,
'transactionTax': tax_price,
'transactionId': "{{ order_number }}",
'transactionProducts': [
{% for line_item in line_items %}
{
'sku': '{{ line_item.sku }}',
'name' : '{{ line_item.title }}',
'price': {{ line_item.line_price | divided_by: 100}},
'quantity':{{ line_item.quantity }}
},
{% endfor %}
]
});
</script> 

And I expected in total_price price with discount. For example: discount order

Expected 2314 but get 2414. How I can get total price with discount???
