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

BigDecimal.byteValueExact介绍

[英]Returns this BigDecimal as a byte value if it has no fractional part and if its value fits to the byte range ([-128..127]). 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适合字节范围（[-128..127]），则将其作为字节值返回。如果不满足这些条件，将抛出算术异常。
