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

BigDecimal.stripTrailingZeros介绍

[英]Returns a new BigDecimal instance with the same value as this but with a unscaled value where the trailing zeros have been removed. If the unscaled value of this has n trailing zeros, then the scale and the precision of the result has been reduced by n.
[中]返回一个新的BigDecimal实例,该实例的值与此实例的值相同,但具有一个未缩放的值,其中尾部的零已被删除。如果未标度的值有n个尾随零,则结果的标度和精度降低了n。
