I do not understand why CEIL should return an integer value. From my
point of view it should return a value of any type that is the ceil
of the parameter. Can you explain a bit better why you think result
must be integer?
I'm only casting it to an integer to ensure the number returned is a
whole number without any digits beyond the decimal point. Without that,
the macro would return 4.5 when executed on CEIL(3.5) instead of 4.
What's the problem with ceil(3)? It is C89.
