BigDecimal abs() Method in Java
-
The java.math.BigDecimal.abs() is used to return a BigDecimal whose value is the absolute value of the BigDecimal and whose scale is this.scale().
Syntax :
public BigDecimal abs()
Parameters: The method does not accept any parameters.
Return Value: Returns a BigDecimal whose value is the absolute value of this BigDecimal scale is this.scale().
Below programs will illustrate the use of java.math.BigDecimal.abs() method :
Program 1
import java.io.*;
import java.math.*;
public class GFG {
public static void main(String[] args)
{
BigDecimal num;
num = new BigDecimal( "-51" );
System.out.println( "Absolute value is " + num.abs());
}
}
|
Output:
Absolute value is 51
Program 2
import java.io.*;
import java.math.*;
public class GFG {
public static void main(String[] args)
{
BigDecimal num;
num = new BigDecimal( "-63.93471" );
System.out.println( "Absolute value is " + num.abs());
}
}
|
Output:
Absolute value is 63.93471

The java.math.BigDecimal.abs(MathContext mc) returns a BigDecimal whose value is the absolute value of the BigDecimal obtained by rounding it off according to the precision settings specified by mc, an object of MathContext class.
Syntax:
public BigDecimal abs(MathContext mc)
Parameters : The function accepts only one parameter mc of MathContext class object, which specifies precision settings to be used for rounding off the BigDecimal.
Return Value: Returns a BigDecimal whose value is the absolute value of this BigDecimal obtained by rounding it off according to the precision settings specified by the object mc.
Exception : The method throws an ArithmeticException, if the result is inexact but the rounding mode is UNNECESSARY.
Below programs illustrate the use of java.math.BigDecimal.abs() method with specified MathContext :
Program 1
import java.io.*;
import java.math.*;
public class GFG {
public static void main(String[] args)
{
BigDecimal num, absv;
MathContext mc = new MathContext( 2 );
num = new BigDecimal( "51.93471" );
absv = num.abs(mc);
System.out.println( "Absolute value, rounded to 2 precision is "
+ absv);
}
}
|
Output:
Absolute value, rounded to 2 precision is 52
Program 2
import java.io.*;
import java.math.*;
public class GFG {
public static void main(String[] args)
{
BigDecimal num, absv;
MathContext mc = new MathContext( 15 );
num = new BigDecimal( "143567812363.93471" );
absv = num.abs(mc);
System.out.println( "Absolute value, rounded to 15 precision is "
+ absv);
}
}
|
Output:
Absolute value, rounded to 15 precision is 143567812363.935
