Try:

    NumberFormat nf = NumberFormat.getInstance();
    nf.setMinimumFractionDigits( 1 );
    nf.setMaximumFractionDigits( 2 );
    System.out.println( nf.format( aNumber ) );

Number format is localized, so a number that formats as "12,345,678.99" 
in a US locale will format as "12.345.678,99" in some other locales.

The NumberFormat object can be re-used, so in many cases, you will want 
to create a single class (static) instance of NumberFormat.
