float floor(float number)
number is the number you want to round.
Examples
Returns 2.
Returns 3.
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
