How to implement the correct count?

Question

JavaScript

when instead of 150.00
I write 1 150, 00 separated by a space,
then there is an incorrect count

23 line for example
------------------------
+ in the second case
where 300 , 44
counts without fractions for some reason

Answer 1

take unprocessed numbers, for example from data-* , and then render them

<p class="basket__single" data-val="300.44"><span>300, 44</span> грн.</p>
