How can I take the numbers after the dot (.) in double?

Question

I'm trying to take the number after the dot (.)

for ex: 5.12 what I want is 0.12

this is my code:-

    double number= 5.12;
    int nInt= (int) number;
    double nDouble= number- nInt;

    if (nDouble== 0.12) {

        System.out.println(nDouble);

    } else {

        System.err.println(nDouble+ "\nThe answer should be (0.12)!!!");
    }

the code should give me 0.12 but it gives me 0.1200000000000001

How to fix this?

if you want to work with numbers which is important for you to get exact value for arithmetic calculation, you can use `BigDecimal` and `BigInteger` in java — Amin, Oct 05 '18 at 12:43
