because of the result of dividing any two numbers in this range, the one with the least error is also more accurate than the floating point number.

floating-point numbers are also divided into direct comparison and indirect comparison.

for example, no matter how the ratio is equal:

        Float f1 = 0.01f;
        Float f2 = 0.09f;
        Float f3 = 0.1f;

        System.out.println(f3 == (f1 + f2)); // true
        System.out.println(f3.compareTo(f1 + f2)); // 0
        System.out.println(f3.equals(f1 + f2)); // true

to Double, is not equal in any way:

        Double d1 = 0.01d;
        Double d2 = 0.09d;
        Double d3 = 0.1d;

        System.out.println(d3 == (d1 + d2)); // false
        System.out.println(d3.compareTo(d1 + d2)); // -1
        System.out.println(d3.equals(d1 + d2)); // false
        System.out.println(Math.abs(d3 - (d1 + d2)) < Double.MIN_EXPONENT); // false
