Usage

From source file:Main.java

public static void main(String[] args) {
    double operation = 890.0 / 1440.0;
    BigDecimal big = new BigDecimal(operation);
    big = big.setScale(4, RoundingMode.HALF_UP);
    double d2 = big.doubleValue();
    System.out.println(String.format("operation : %s", operation));
    System.out.println(String.format("scaled : %s", d2));
