Returns a BigDecimal whose value is the absolute value of this BigDecimal , and whose scale is this.scale() .

Usage

From source file:Main.java

public static void main(String[] args) {

    // assign value to bg1
    BigDecimal bg1 = new BigDecimal("-40");

    // value before applying abs
    System.out.println("Value is " + bg1);

    // assign absolute value of bg1 to bg2
    BigDecimal bg2 = bg1.abs();

    // print bg2 value
    System.out.println("Absolute value is " + bg2);
}

From source file:MainClass.java
