- The java.math.BigDecimal.plus() is an inbuilt method in java that returns a BigDecimal whose value is (+this), and whose scale is this.scale(). This method, which simply returns this BigDecimal is included for symmetry with the unary minus method negate().
Syntax:
public BigDecimal plus()
Parameters: The function does not accepts any parameter.
Return value: This method returns the object value i.e., this.
Below program illustrates the working of the above mentioned method:
Program 1:
// Java program to demonstrate the
// plus() method
import java.math.*;
public class Gfg {
public static void main(String[] args)
{
// Assign value to b1
BigDecimal b1 = new BigDecimal("-45.652");
// Assign the result of plus method on
// BigDecimal Objects b1 to b2
BigDecimal b2 = b1.plus();
// Print the value of b2
System.out.println("The value of the BigDecimal is " + b2);
}
}
Output:
The value of the BigDecimal is -45.652
Program 2:
// Java program to demonstrate the
// plus() method
import java.math.*;
public class gfg {
public static void main(String[] args)
{
// Assign value to b1
BigDecimal b1 = new BigDecimal("7458.3256");
// Assign the result of plus method on
// BigDecimal Objects b1 to b2
BigDecimal b2 = b1.plus();
// Print the value of b2
System.out.println("The value of the BigDecimal is " + b2);
}
}
Output:
The value of the BigDecimal is 7458.3256
- The java.math.BigDecimal.plus(MathContext mc) is an inbuilt method in java that returns a BigDecimal whose value is (+this), with rounding according to the context settings.
Syntax:
public BigDecimal plus(MathContext mc)
Parameters: This method accepts a single parameter mc which refers to the context of rounding to use i.e., up to what digit the value would be rounded.
Return value: This method returns the value of BigDecimal Object, rounded as necessary. A zero result will have a scale of 0.
Below program illustrates the working of the above mentioned method:
Program 1:
// Java program to demonstrate the
// plus() method
import java.math.*;
public class gfg {
public static void main(String[] args)
{
BigDecimal b1 = new BigDecimal("-452.325");
MathContext m = new MathContext(4); // 4 precision
// Perform plus on BigDecimal Objects b1 using m
BigDecimal b2 = b1.plus(m);
// Print the value of b2
System.out.println("Result of plus is " + b2);
}
}
Output:
Result of plus is -452.3
Program 2:
// Java program to demonstrate the
// plus() method
import java.math.*;
public class gfg {
public static void main(String[] args)
{
BigDecimal b1 = new BigDecimal("-10.325");
// 4 precision
MathContext m = new MathContext(4);
// Perform plus on BigDecimal Objects b1 using m
BigDecimal b2 = b1.plus(m);
// Print the value of b2
System.out.println("Result of plus is " + b2);
}
}
Output:
Result of plus is -10.33
