Floats and integers

Floats and integers represent rational numbers with and without a decimal part, respectively. Those types are quite intuitive to use, as they can be added, subtracted, multiplied, divided, and more. Let's take a look at the following example. First, we assign two variables:

A = 6B = 5

Now, let's go over some possible operations:

>>> A + B11>>> A - B1>>> A / B1.2>>> A * B30

You can also raise numbers to a power by using double asterisks:

>>> 2**38>>> 3**29

You might have noticed that the division of two integers will result in a float. This happens even if the remainder is zero:

>>> 10 / 25.0

If you need to keep the integer division result as an integer (rounded, if needed), then use a double slash instead; this operation ...
