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. its demotion of value.

Also take long bb; instead of int as int has value 32767 as its high value.

Try

fbb = bb/1000.000;

or

fbb = (double)bb/1000;
