BigDecimal.valueExact介绍

[英]If intVal has a fractional part throws an exception, otherwise it counts the number of bits of value and checks if it's out of the range of the primitive type. If the number fits in the primitive type returns this number as long, otherwise throws an exception.
[中]如果intVal有一个小数部分，则抛出异常，否则它将计算值的位数并检查它是否超出原语类型的范围。如果该数字与基元类型匹配，则返回该数字，否则抛出异常。
