Division int and double
We will not stop on most operations since they work as expected. Instead, let's look at the reasons behind the incorrect result obtained from the division operation. Those are explained in a video below:
It's not just a problem limited to division. When you use operators such as +, -, *, or / on variables of certain types, the resulting value will have the same type as the operands.
It's important to be mindful of these possibilities and take them into account.

- Calculate and output how many meters in a given number of kilometers (
2455). - Make sure the output number is float and not integer.
Note
In order to get the correct result, we only need to add
.to any of the numbers in division (9/4.or9./4or9./4.).
