I like this.
However, one has to add a comment line mentioning that it works
funny with negative numbers. Otherwise, it will jump up and bite
you months or years down the road.
Standing on Gary's shoulders, I suggest something like this to
handle negative numbers, too:
function ceiling n
if trunc(n)=n then
return n
else
if n>0 then
return trunc(n)+1
else
return trunc(n)
end if
end if
end ceiling
Once you get the bugs out of it (I typed it in off the top of my
head), this function will last you a lifetime. The ceiling
function is found in many calculation methods and has an
agreed-upon meaning.
