Those are the values, they are NOT just how they are displayed!

The problem is that your input values are integer (probably uint8), which means that the outputs are integer class too. You can check this easily yourself. The simple solution is to convert the input data to double before the division:

factor = (double(g)/double(b))/double(r)
