You need to check for integer values:

getceil (5) --> 6
getfloor (-5) --> -6

And you need to check for 0:

getceil (0) --> error: the variable y is not defined

I don't know if you're checking prior to calling these functions (in which
case you may be OK), otherwise you need to add that check to the functions.

on getceil(x)
set y to x as integer
if x is not equal to y then
if x > 0 then return y + 1
if x < 0 then return y - 1
end if
return y
end getceil
