Answer 1

I'm not sure whether you have trouble formatting the output of a decimal number, or calculating it (or maybe something else entirely). Some more information would be helpful, such as:
- a code snippet detailing your problem
- more information to what you are trying to do
- a description of actual behaviour vs expected behaviour
- maybe a certain input that triggers unwanted behaviour
Linking your own question, on the other hand, is unfortunately not very helpful.

EDIT: I discovered the post you were probably trying to refer to:

While changing the definition to

float purchaseAmount = 0;

is a step in the correct direction, you also need to take into account that integer division yields an integer by default. In order to get a floating-point number, at least one operand must be one itself. Therefore, you also need to do something like the following in the loop:

purchaseAmount = (totalPrice * 15) / 100.0;

Answer 2

For instance, getting an output as float you need to do "type casting"

Although refering to the post i clearly see that everything is defined as integer and all other values {that's used for doing *,/,()} are integer, that's why you got your output as integer.

Answer 3

The definition of the variables as integer is from sololearn
