Description
The floor() function returns the largest integer that is not greater than argument, that is, the greatest integer lower bound for argument.
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.
Example
The following floor() function call prints the integer 12:
print(floor(12.3456));
