Floor fun in c.
Rounds downs the nearest integer.
Returns the largest integer that is smaller than or equal to x i e.
As a side note in c empty list means function can only be called without any parameter.

The floor function returns the largest integer value that is smaller than or equal to a number.
Also look at the ceiling and round functions.
The floor function a solid dot means including and an open dot means not including.
In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively.
In c it is not a good idea to declare a function like fun.
