Returns a BigDecimal whose value is (this / divisor) , and whose scale is as specified.

Usage

From source file:Main.java

public static void main(String[] args) {

    BigDecimal bg1 = new BigDecimal("16");
    BigDecimal bg2 = new BigDecimal("3");

    // divide bg1 with bg2 with 3 scale
    BigDecimal bg3 = bg1.divide(bg2, 3, RoundingMode.CEILING);

    System.out.println(bg3);/* w w  w  . ja v a2s . c  om*/
}

From source file:Main.java

public static void main(String[] args) {

    // divide bg1 with bg2 with 4 scale
    // 1 specifies BigDecimal.ROUND_DOWN
    BigDecimal bg3 = bg1.divide(bg2, 4, BigDecimal.ROUND_DOWN);

    System.out.println(bg3);/*w w w.j a v a  2s.com*/
