Arithmetic operators: multiplication

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.
