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
Returns 2.
Returns 3.
If Head.height is -2.8,
this returns -3.
TipYou 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
