turtle:18: Expected number

Hi,

I wrote this program and whenever I try to run it, I get the error in the title. Even if I change the program/add more lines I keep getting the same error. It's probably something really simple, but I can't find it. Help is greatly appreciated :)/>

what do these functions do? can you please post the code?

check.whole(z)
check.positive(z)

The code for the API functions are in the commented links, but here and here are the links. Basically it checks to see if the variable is whole and positive.

oh oops, so used to not reading peoples comments that I didn't even notice them…

gimme a sec.

ok so I cannot seem to replicate the problem.

however I do get an error for the function checkSlot
you must declare the slot variable above this function.

Side Note: Here is a better CheckAPI

Spoiler

function even(var)
  return var % 2 == 0 -- % is shorthand for math.fmod
end

function odd(var)
  return not var % 2 == 0
end

function whole(var)
  return var % 1 == 0
end

function positive(var)
  return var >= 0 -- alternatively you could do  var == math.abs(var)
end

Thanks for the better API. Just wanted to point out that in the odd function you provided, it's missing a check for a whole number (e.g. 1.5 would be considered odd). But that's an easy fix.

Also, declaring the slot variable before the function seems to have solved the problem. Thanks :)/>

Oh yes, sorry I did miss that off. like you said, easy fix

return not even(var) and (var % 1 == 0)

but iirc your old whole was a little wonky because you were checking the % came to 0.5 which means it wouldn't have been whole.

Cool cool, no problems.
