The java.math.BigDecimal.scale() is an inbuilt method in java that returns the scale of this BigDecimal.
- For zero or positive value, the scale is the number of digits to the right of the decimal point.
- For negative value, the unscaled value of the number is multiplied by ten to the power of the negation of the scale.
Syntax:
public int scale()
Parameters: This method does not accepts any parameter.
Return value: This method returns the scale of this BigDecimal object.
Below program illustrates the working of the above mentioned method:
Program 1:
// Java program to demonstrate the// scale() method import java.math.*; public class Gfg { public static void main(String[] args) { BigDecimal b1 = new BigDecimal("456.0"); BigDecimal b2 = new BigDecimal("-1.456"); // Assign the result of scale on // BigDecimal Objects b1, b2 to int objects i1, i2 int i1 = b1.scale(); int i2 = b2.scale(); // Print the values of i1, i2; System.out.println("The scale of " + b1 + " is " + i1); System.out.println("The scale of " + b2 + " is " + i2); }} |
Output:
The scale of 456.0 is 1 The scale of -1.456 is 3
Program 2:
// Java program to demonstrate the// scale() method import java.math.*; public class Gfg { public static void main(String[] args) { BigDecimal b1 = new BigDecimal("745"); BigDecimal b2 = new BigDecimal("-174"); // Assign the result of scale on // BigDecimal Objects b1, b2 to int objects i1, i2 int i1 = b1.scale(); int i2 = b2.scale(); // Print the values of i1, i2; System.out.println("The scale of " + b1 + " is " + i1); System.out.println("The scale of " + b2 + " is " + i2); }} |
Output:
The scale of 745 is 0 The scale of -174 is 0
