Checking if the result is a natural number

-----------------------------------

What is it you are trying to achieve?
After dividing a number, I want to see if it really IS divisible by finding out if the number outputted was natural, or decimal

What is the problem you are having?
Don't know if turing can do that or not

Please specify what version of Turing you are using
4.0.5

look up, the term mod.

That should be more then enough for you.

And, yes it can.

if num mod 2 = 0 
then

end if


wouldnt that just check if the number is even?

num mod 2 would test if it's divisible by two. You'd replace two with whatever number you need to check if you can divide by.

Another way,,

[code]
if num div X = num/X then
   ...
end if
[/code]

Although that method is slower and makes less sense..

Re: Checking if the result is a natural number

I like my method.

if num = floor(num) then
put "Integer"
else
put "Real Number"
end if

Hmm, seems like the smallest amount of code to me, nice.
