I need to write, in 1 code line, given a number (pos, neg, int, float), how do I round it without preset functions like fix, round, etc.?

In general people on MATLAB Answers don't post answers to homework questions or questions that sound like homework. If you show what you've done to try to solve the problem on your own and ask a specific question about where you're having difficulty you may receive some more specific suggestions.
Of course, if this isn't a homework problem, just use the round function or the other rounding functions included in MATLAB.

Try it:
x = 13.3
y = mod(x, 1)
z = 13.6
y = mod(x, 1)
Now you should see how to use the output to decide, if the rest of the division by 1 is lower or higher than 0.5.

int64() rounds also. And you can use cast() to preserve the original class.
