CEILING(<num>)
This is a ‘rounding’ function but different in that it always rounds up to the
integer above. Mainly of interest to programmers.
Eg. CEILING(3.2) = 4
CEILING(32.99) = 33
CEILING((12+ 6)/7)
= CEILING(2.0642…) = 3
Note: CEILING(-2.56) = -2 not -3. The
CEILING function rounds up to the next
integer above, which is -2.

DEG RAD(<deg>)
This function converts degrees to radians.
Eg. DEG RAD(30) = 0.5235…
DEG RAD(180) = 3.1415926…

FLOOR(num)
This function is the same as the CEILING
function, except that it always rounds down.
Eg. FLOOR(3.75) = 3
FLOOR(45.01) = 45
Note: FLOOR(-2.56) = -3 not -2.
The FLOOR function is the same as the
mathematical function ‘greatest integer’ which
is studied in many mathematical courses.
If you want to graph the greatest integer
function then you will need to use the PLOT SETUP view to turn off CONNECT
first, since the graph is supposed to be a discontinuous step function. The
result with CONNECT turned on is not good.
