double d=3.95;
System.out.printf("%.1f",d);
output is 4........
so 3.95 gets rounded to 4.....3.91 to 3.92 is rounded to 3.9 and 3.95 to 3.99 is rounded to 4.0



output is 124 4.0

is there any other rule that i should know about or this is it......

Not sure why you want to use the

%.0f %.1f
option.

If you just print:

System.out.printf(d1 + " " + d2);

Will show you the desired effect.

Else Use java.text.DecimalFormat
