How to add function to change dot to comma in price number and round it to two decimal

Answer 1

You can use “.toFixed(x)” function to round your prices:

price1 = price1.toFixed(2)

And then you can use method “.toString()” to convert your value to string:

price1 = price1.toString()

Also, you can use method “.replace(“..”,”..”)” to replace “.” for “,”:

price1 = price1.replace(".", ",")

Result:

price1 = price1.toFixed(2).toString().replace(".", ",")

Updated answer

.toFixed already returns a string, so doing .toString() is not needed.
This is more than enough:

price1 = price1.toFixed(2).replace(".", ",");
