2.1.3.3 Operators - data manipulation tools

Arithmetic operators: multiplication

An * (asterisk) sign is a multiplication operator.

Run the code below and check if our integer vs. float rule is still working.

print(2 * 3) print(2 * 3.) print(2. * 3) print(2. * 3.)

Arithmetic operators: division

A / (slash) sign is a divisional operator.

The value in front of the slash is a dividend, the value behind the slash, a divisor.

Run the code below and analyze the results.

print(6 / 3) print(6 / 3.) print(6. / 3) print(6. / 3.)

You should see that there is an exception to the rule.

The result produced by the division operator is always a float, regardless of whether or not the result seems to be a float at first glance: 1 / 2, or if it looks like a pure integer: 2 / 1.

Is this a problem? Yes, it is. It happens sometimes that you really need a division that provides an integer value, not a float.

Fortunately, Python can help you with that.
