Round Function

[Sofia]

Hello
I am creating my online store in prestashop 1.7.3.3 and I came across some errors in the rounding of values.
When I write a function in php like this:
{Tools :: displayPrice (round (($ product.price) /1.23), 2)}
If for example the product.price is 35 €, it shows the result of 28.00. But the correct value is 26.02.

What function can I use for this not to happen?
