How do I write an if statement that checks if N is an integer and if it is not then you use ceil function to round it.

N is your number.
if(mod(N,1) == 0)
fprintf("i% is a integer \n", N);
else
N = ceil(N)
end

mod(N,1)
Find the modulus of N divided by 1.
if mod (N, 1) = 0, N is an integer since there is no remainder.
for example:
mod(2,1) % ---> 0
2/1 = 2 (remainder 0)
mod(2.3,1) % ---> 0.3
2.3 / 1 = 2 (remainder 0.3)
