本文整理了Java中java.math.BigDecimal.intValueExact()方法的一些代码示例，展示了BigDecimal.intValueExact()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.intValueExact()方法的具体详情如下：
包路径：java.math.BigDecimal
类名称：BigDecimal
方法名：intValueExact

BigDecimal.intValueExact介绍

[英]Returns this BigDecimal as a int value if it has no fractional part and if its value fits to the int range ([-231..231-1]). If these conditions are not met, an ArithmeticException is thrown.
[中]如果此BigDecimal没有小数部分，并且其值符合int范围（[-231..231-1]），则将其作为int值返回。如果不满足这些条件，将抛出算术异常。

代码示例

long aLong = ...;
int anInt = new BigDecimal(aLong).intValueExact(); // throws ArithmeticException
                          // if outside bounds

  }
  int scale = decimal.scale();
  if (scale >= -100 && scale <= 100) {
    return decimal.intValue();
  }
  return decimal.intValueExact();
}
