If Statement to identify integer

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

Instead of mod you can use isinteger.

[Julissa Pou]

What does the (N,1) do? Can you leave it as mod(N)?

[Bruno Luong]

I think isinteger does not do what you expect Timo

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)
