I already know the basic rules for the both functions:
$$\text{Ceil}(2.5)=3\\ \text{Floor}(2.5)=2$$
But I could not understand the following these:
$$\text{Ceil}(2.6, 0.25)=2.75\\ \text{Floor}(2.6, 0.25)=2.5$$
Why is there a second parameter? How Could I calculate the that to obtain the results above?
PS: I already been researching on google and books, but I only could get what I already know.
Thanks for your collaboration.
Ceil
andFloor
functions of some programing language, and in that case which programming language you are talking about certainly seems to be a significant piece of information useful for anyone who is trying to help you... Then again, you may be not talking about a programming language at all. Who knows! :-) $\endgroup$ – Mariano Suárez-Álvarez Apr 26 '15 at 0:30
