Returns a number rounded to the largest integer less than or equal to a floating point number.
float floor(float number)
number is the number you want to round.
Examples
floor(2.344)
Returns 2.
floor(3.0)
Returns 3.
floor(Head.height)
If Head.height is -2.8, this returns -3.
Tip:
You can use floor for rounding to the nearest number (for example, rounding 2.75 up to 3 and rounding 2.25 down to 2). Simply create a function that adds 0.5 to the number before using floor; this will get the right results:
floor (2.25 + .5) = 2 floor (2.75 + .5) = 3
