As I mentioned in the comments, you can subtract 0.1 before calling Math.round. Like,

DoubleStream.of(1.4, 1.5, 1.59, 1.6)
        .mapToInt(x -> (int) Math.round(x - 0.1))
        .forEach(System.out::println);

Outputs (as requested)

1
1
1
2

Since you want from .6 it will be ceiling the value then use this

x = Math.floor(x + 0.4);
