Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("-999999");
    BigDecimal bg2 = new BigDecimal("3.3E+10");

    // assign the long value of bg1 and bg2 to l1,l2 respectively
    long l1 = bg1.longValueExact();
    long l2 = bg2.longValueExact();

    // print l1,l2 values
    System.out.println(l1);/*  w  w w  .j a  v a 2s  .  co m*/
    System.out.println(l2);
