1 and 2 are integers (ints). They can only represent whole numbers, and doing arithmetic with them (+, -, *, /) will only give you integer answers. The fraction part will be thrown away.
To do maths with higher precision, try:
Code:
// adding the decimal point to an int makes it
// into a float and enables the extra precision
float scala = 1.0/2.0;
println(scala);

Hope that helps.
