Question

How would I CORRECTLY round a BigDecimal to the nearest whole value?

For instance

1.2 --> 1

1.5 --> 2

1.6 --> 2.

I tried

BigDecimal val = new BigDecimal(1.5);
System.out.println(val.setScale(0, RoundingMode.HALF_UP))

But this still gives me 1. NOT 2 as anticipated.

Does anyone happen to know how to correctly do this?

Thanks

Answer 1

    BigDecimal val = new BigDecimal(1.2);
    System.out.println(val.setScale(0, RoundingMode.HALF_UP));
    val = new BigDecimal(1.5);
    System.out.println(val.setScale(0, RoundingMode.HALF_UP));
    val = new BigDecimal(1.6);
    System.out.println(val.setScale(0, RoundingMode.HALF_UP));

Result:

1

2

2

I don’t see where is the problem
