How I can display or keep double values to 2 decimal points?
textContent: 'Total Payable: ' + '€'+finalPrice.toString(),
I need to know how to ensure that
double finalPrice;
that finalPrice is always displayed to 2 decimal points. Whether it is converted to a string or not.
I've tried everything and called my MP.
double finalPrice = 0.00;
I noticed that initialising it as 0.00 seems to do something, but I need something a bit more solid.
The expected result is the client should pay for what they've purchased. The actual result is we are charging the customer a bit more than what they've purchased

Just use %. 2f as the format specifier. This will make the Java printf format a double to two decimal places.
By using a button: Select the cells that you want to format. On the Home tab, click Increase Decimal or Decrease Decimal to show more or fewer digits after the decimal point.
we now see that the format specifier "%. 2f" tells the printf method to print a floating point value (the double, x, in this case) with 2 decimal places.
format() with “{:. 2f}” as string and float as a number. Call print and it will print the float with 2 decimal places.
double d = 1.5124;
String number = d.toStringAsFixed(2); // 1.51
Even if you have
double d = 1.51 // number: 1.51
double d = 1.5 // number: 1.50
double d = 1 // number = 1.00
You can see you will always have 2 decimal places with toStringAsFixed(2).
