Answer 1

Use float or double if you need precision. Int contains whole numbers, so in division the precision is "cut off".

Answer 2

What you should do to avoid it are two things:
1. Declare x as float or double
2. Write the division expression with at least one of the arguments as a floating point number, like this:
