Java get decimal value
We can also get the decimal value in the specified
format as we wish by calling DecimalFormat class. It will format a long
value to the specified string pattern.
DecimalFormat dec = new DecimalFormat("###.##");
System.out.println(dec.format(12345.6789));
Above lines of code prints decimal value 12345.6789 in
the 12345.68 format. Also we can print this decimal value in other different
formats by defining the decimal format pattern. Here is the full example code
for GetDecimalValue.java as follows:
GetDecimalValue.java
import java.util.*;
import java.text.*;
public class GetDecimalValue
{
public static void main(String args[]) {
// Decimal Value in the 12345.68 format
// By rounding the last digit
DecimalFormat dec = new DecimalFormat("###.##");
System.out.println(dec.format(12345.6789));
// Decimal Value in the 12345.679 format
// By rounding the last digit
dec = new DecimalFormat("###.###");
System.out.println(dec.format(12345.6789));
// Decimal Value in the 12345.7 format
// By rounding the last digit
dec = new DecimalFormat("###.#");
System.out.println(dec.format(12345.6789));
}
