类名称：BigDecimal
方法名：byteValue

BigDecimal.byteValue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。
