当double 必须用作 BigDecimal 的源时,请注意,此构造方法提供了一个准确转换;它不提供与以下操作相同的结果:先使用 Double.toString(double) 方法,然后使用 BigDecimal(String) 构造方法,将 double 转换为 String。要获取该结果,请使用 static valueOf(double) 方法。 参数: val - 要转换为 BigDecimal 的double ...

Otherwise, zeros may be appended to reach the precision. For a canonical representation of the value, use Float#toString(float) or Double#toString(double) as appropriate. 'a' '\u0061' Requires the output to be formatted in hexadecimal exponential form. No localization is applied. The...
