BigDecimal()的使用

public static void main(String[] args) {Double price = 666.66;Long money1 = (new BigDecimal(price)).multiply(new BigDecimal(100)).longValue();Long money2 = (new BigDecimal(price)).multiply(new BigDecimal(100)).divide(new BigDecimal(1), 1, BigDecimal.ROUND_HALF_UP).longValue();System.out.println(money1);System.out.println(money2);}

money1   =====   666.65             money2 ====666.66
