Function to check if a number is divisible by 5

How can I write a function m.file that takes as input a real number and checks to see if it is divisible by 5. An appropriate message indicating the result should be the output.
I have tried to write this but it dosen't seem to work as I need the user to input a number and check if it is divisble by 5
function [resp] = div5(x)
if (rem(x,5) == 0)
resp = 1;
else
resp = 0;
end
Thanks in advance

No you would use the code from before and then at the command line
div5(10)

bro it must be like this, check it my function
function [a] = div5(x)
% [x] = div5(x) - to checks a real number if it is divisible by 5.
for a=rem(x,5)
if a~=0
[a] ='NOT divisible by 5.';
else
[a] ='divisible by 5.';
end
end
end

% check "a" is divisible by "b" or not
function test = divisibility_test(a,b)
if ceil(a/b)-a/b==0
test = true;
else
test=false;
end
end

The output of
ceil(a/b)-a/b==0
is a logical array, and the first conditional is only executed if every element of that array is true. So the whole thing simplifies to
function test = divisibility_test(a,b)
test = all(ceil(a/b)-a/b==0);
end
or just
function test = divisibility_test(a,b)
test = all(~mod(a,b));
end
