NumberUtils.getScale(1.12346);
NumberUtils.setScale(1.1246, scale: 2, roundingMode: ROUND_UP);

int a = NumberUtils.add(1, 2);
double b = NumberUtils.add(1, 2, returnType: double);

NumberUtils.add(0.3, 0.6);
NumberUtils.subtract(0.3, 0.2);
NumberUtils.multiply(0.3, 1.5);
NumberUtils.divide(0.3, 0.1);

NumberUtils.multiply(1.2354, 2.365, scale: 2);
NumberUtils.divide(12354, 7, scale: 5, roundingMode: ROUND_HALF_UP);

DateUtils.format(time, "yyyy.MM.dd");

DateTime time1 = DateUtils.today();
DateTime time2 = DateUtils.today(hour:9);
DateTime time3 = DateUtils.yesterday();
DateTime time4 = DateUtils.set(DateTime.now(), year:2017);
DateTime time5 = DateUtils.truncate(DateTime.now(), hour:9, minute:30);
DateUtils.truncatedEquals(time1,time2,DateUtils.MONTH);
DateUtils.truncatedEquals(time1,time5,DateUtils.DAY);
DateUtils.daysOfTheMonth(time1);
