Why is this simple piece of code not working?

Question

I am trying to get a floating variable accurate to just 3 decimal points for a comparison calculation. I am trying the method below, but it doesn\'t work. I can\'t see why not,

Answer 1

When you perform

 fbb = bb/1000;

It treats operation as int/int and returns an int

Try

fbb = ((double)bb)/1000.000;

It will be treated as (double)/(double) and return a double.
