强制点(“.")作为java中的小数分隔符
我目前使用以下代码打印双精度:
I currently use the following code to print a double:
return String.format("%.2f", someDouble);
这很好用,除了 Java 使用我的语言环境的小数分隔符(逗号)而我想使用点.有没有简单的方法可以做到这一点?
This works well, except that Java uses my Locale's decimal separator (a comma) while I would like to use a point. Is there an easy way to do this?
推荐答案
使用String.format
可让您指定语言环境:
Use the overload of String.format
which lets you specify the locale:
return String.format(Locale.ROOT, "%.2f", someDouble);
如果您仅 格式化数字 - 就像您在这里一样 - 那么使用 NumberFormat
可能更合适.但是,如果您需要 String.format
的其余格式化功能,这应该可以正常工作.
If you're only formatting a number - as you are here - then using NumberFormat
would probably be more appropriate. But if you need the rest of the formatting capabilities of String.format
, this should work fine.
