Test for integer value

I am trying to make a battleship styled game, one of the parts involve getting a set of user input 'firing coordinates', which I then need to test to make sure it is an integer value 1 through 10, what function can I use to test that it is an integer?

*edit: I am looking for a logical operator or else condition that can specify a non integer input.

Answer 1

See the following:

doc fix
doc ceil
doc floor
doc round

E.g., for a scalar x

if( round(x) == x )
    % x is an integer

[Corey Washburn]

I am not looking for a way to make a decimal value into an integer (round 4.3 to 4) I am looking for a logical operator that is false if the input is not an integer value.

That's exactly what my code does ...

Answer 2

[Bruno Luong]

Perhaps no better no worse than James's solution just different

iswholenumber = mod(x,1)==0

Answer 3

[Bruno Luong]

according to my test slightly faster, but need to assume the smaller range of x of be working:

x == int32(x)
