formatting floating point problem

[Erwin Kalvelagen <erwin dot kalvelagen at gmail dot com>]

Hi,

I am wondering what I am doing wrong here.

erwin@erwin-laptop:~/jtest$ cat tst.java
public class tst {

	public static void main(String[] args) {
		double d = 0.8;
		System.out.format("[%g]%n",d);
	}
}
erwin@erwin-laptop:~/jtest$ gcj --main=tst tst.java
erwin@erwin-laptop:~/jtest$ ./a.out
[]
erwin@erwin-laptop:~/jtest$ gcj -v

With Sun's java I get actually something printed.


Thanks, Erwin
