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
