Customizing Odoo POS receipt. I was able to insert client's name but no change in the unit price. What is wrong with my code? - receipt

Question

I was able to add the customer's name on the receipt but I can't replace the unit price.
My goal is to display the unit price in its non-rounded form (in this case 5.60 and not 6).
Currently, the POS shows the correct form:
product 1
11pk at 5.60/pk = 62
but after validating the payment, the receipt would round off all the unit prices and would print this:
product 1
11pkx6 = 62
This is my code in my custom pos receipt xml file:
<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
<t t-name="OrderReceipt" t-inherit="point_of_sale.OrderReceipt" t-inherit-mode="extension" owl="1">
<xpath expr="//div[#class='pos-receipt-contact']" position="inside">
<t t-if='receipt.client'>
<div>Client:
<t t-esc='receipt.client.name' />
</div>
</t>
</xpath>
</t>
<t t-name="OrderLinesReceipt" t-inherit="point_of_sale.OrderLinesReceipt" t-inherit-mode="extension" owl="1">
<xpath expr="//div[#class='pos-receipt-left-padding']" position="replace">
<t t-esc="Math.round(line.quantity * Math.pow(10, env.pos.dp['Product Unit of Measure']))/ Math.pow(10, env.pos.dp['Product Unit of Measure'])"/>
<t t-if="!line.is_in_unit" t-esc="line.unit_name" />
x
<t t-esc="line.price_display_one" />
<span class="price_display pos-receipt-right-align">
<t t-esc="env.pos.format_currency_no_symbol(line.price_display)" />
</span>
</xpath>
</t>
</templates>
The code to insert customer name worked but no indication that the code to replace the unit price worked.
