Arithmetic operators: multiplication and division

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.)

It is.

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 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 

It this a problem? Yes, ti 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.
