使用Double 转 BigDecimal 并保留两位小数出现异常: java.lang.ArithmeticException: Rounding necessary 的原因是:精度丢失。 setScale(int newScale) 方法内部调用 setScale(int newScale, int roundingMode) 方法,传入默认舍入模式:ROUND_UNNECESSARY,

Double 转 BigDecima l并保留两位小数出现异常: java.lang.ArithmeticException: Rounding necessary 。 代码如下: public static void main(String[] args) { Double d1 = 0.10; BigDecimal bigDecimal1 = new BigDecimal(d1).setScale(2); System.out.println(bigDecimal1); // 或 Double d2 = 0.123; BigD...
In Java, truncation means rounding down towards zero. True | False 7. Converting all data types into integers will yield an acceleration equal to 1.4 meters per second squared. True | False 8. Using double data types for the program will give a truncated value. Answer Key True False...
