Specifying Precision
<![CDATA[
A precision specifier can be applied to the %f, %e, %g, and %s format specifiers.
When applying to floating-point data using the %f, %e, or %g specifiers,
it determines the number of decimal places displayed.
The default precision is 6.
For example, %10.4f displays a number at least ten characters wide with four
decimal places.
import java.util.Formatter;
public class MainClass {
public static void main(String args[]) {
Formatter fmt;
fmt = new Formatter();
fmt.format("%1.4f", 1234567890.123456789);
System.out.println(fmt);
}
}
1234567890.1235
