Math.ceil and Math.floor returning same value

Question

I have a double (23.46)

And using the methods Math.ceil and Math.floor and parsing my double to these methods, I get the same value returned to me, which is 23...

Answer 1

How do you do the actual invocation? I cannot replicate your result, using either the double object or the primitive type.

This code:

    Double d_object = new Double(23.46);
    double d_simple = 23.46;

    System.out.println("Ceiling simple: " + Math.ceil(d_simple));
    System.out.println("Floor simple: " + Math.floor(d_simple));

    System.out.println("Ceiling object: " + Math.ceil(d_object));
    System.out.println("Floor object: " + Math.floor(d_object));

gives me:

Ceiling simple: 24.0
Floor simple: 23.0
Ceiling object: 24.0
Floor object: 23.0
