本文整理了Java中java.math.BigDecimal.intValue()方法的一些代码示例，展示了BigDecimal.intValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。BigDecimal.intValue()方法的具体详情如下：
包路径：java.math.BigDecimal
类名称：BigDecimal
方法名：intValue

BigDecimal.intValue介绍

[英]Returns this BigDecimal as an int value. Any fractional part is discarded. If the integral part of this is too big to be represented as an int, then this % 232 is returned.
[中]将此BigDecimal作为int值返回。任何小数部分都将被丢弃。如果此函数的整数部分太大，无法表示为int，则返回此%232。

public static int extractNanosecondDecimal(BigDecimal value, long integer)
  {
    // !!! 14-Mar-2016, tatu: Somewhat inefficient; should replace with functionally
    //   equivalent code that just subtracts integral part? (or, measure and show
    //   there's no difference and do nothing... )
    return value.subtract(new BigDecimal(integer)).multiply(ONE_BILLION).intValue();
  }
}
