Usage

From source file:Main.java

public static double roundDouble(double v, int scale) {

    if (scale < 0) {

        throw new IllegalArgumentException(

                "The scale must be a positive integer or zero");

    }// ww  w  . j a  v  a  2  s .  co  m

    BigDecimal b = new BigDecimal(Double.toString(v));

    BigDecimal one = new BigDecimal("1");

    return b.divide(one, scale, BigDecimal.ROUND_HALF_UP).doubleValue();

}
