BigDecimal round() Method in Java
The java.math.BigDecimal.round(MathContext m) is an inbuilt method in Java that returns a BigDecimal value rounded according to the MathContext settings. If the precision setting is 0 then no rounding takes place.
Syntax:
public BigDecimal round(MathContext m)
Parameters: The method accepts a single parameter m which refers to the context to use that is the value up to which the BigDecimal value is to be rounded off.
Return value: This method returns a BigDecimal rounded according to the MathContext settings.
Below programs illustrate the working of java.math.BigDecimal.round(MathContext m) method:
Program 1:
import java.math.*;
public class Gfg {
public static void main(String[] args)
{
BigDecimal b1 = new BigDecimal( "4.2585" );
MathContext m = new MathContext( 4 );
BigDecimal b2 = b1.round(m);
System.out.println( "The value of " + b1 +
" after rounding is " + b2);
}
}
|
Output:
The value of 4.2585 after rounding is 4.259
Program 2:
import java.math.*;
public class gfg {
public static void main(String[] args)
{
BigDecimal b1 = new BigDecimal( "-4.2585" );
MathContext m = new MathContext( 4 );
BigDecimal b2 = b1.round(m);
System.out.println( "The value of " + b1 +
" after rounding is " + b2);
}
}
|
Output:
The value of -4.2585 after rounding is -4.259
