Thanks for all the responses guys, I just didn't really know where to
look. I guess for future reference, I really ought to look more at
math.h and other such files.

I'm not a C expert, so apologies for this one:
Basically, I want to take a double and get its closest positive
integer. I haven't been able to find anything that does what I want
(I have a feeling it might be a modulus?).
Anyway, it seems to me I have 3 options:
1. There is an existing, simple function in C - if so can someone
tell me what it is ? :)
2. Do the incredibly clunky, square variable, find square root
3. Write my own function.
It isn't a question of being a C expert. Use the headers, use the
docs. Look
in math.h. If you don't know what the functions do, and you don't
have K&R,
use Xcode's help. For example, search on "fabs". It contains links
to the
rest of what you probably want to know. m.
