unless this just isnt possible, im getting an error saying that assigned value is the wrong type
code: 
function modX (x, y : real) : int
var imod : int
imod := x mod y % error given for y
result imod
end modX

is there any way to complete this without changing the variable type?

you cant use real numbers in coordinates or sizes or anything like that, they have to be integers, because you cant use half of a pixel..

well mod just tells you if it devides compleatly into the number.
so
code: 
function modReal(num1:real, num2:real):real
if (num1/num2) = round(num1/num2) then
result 0
else
result (num1/num2)  floor(num1/num2)
end if
end modReal
put modReal(10.2, 2.5)

the result should be 0.08... code is theoretical as I dont have compiler nearby at the moment... I need someone to confirm that this works

mod gives you a remainder of the division.
modReal acts in the same way as mod, but since both numbers can be real now, so is the remainder.
