Parameter	Definition

The floor() function and the ceil() function together bracket argument such that the following are true:

If argument is an integer, ceil( argument ) = argument = floor( argument ).

If argument is not an integer, floor( argument ) < argument < ceil( argument ) and ceil( argument ) = floor( argument ) + 1.

print(floor(12.3456));
