如何获取NSDecimal或NSDecimalNumber的无格式字符串表示形式？ [英] How to obtain an unformatted string representation of an NSDecimal or NSDecimalNumber?

问题描述

我有一个NSDecimal，需要这个技术字符串，即没有任何格式。浮点应该是一个。如果有任何，和减号应该只是一个 - 如果有任何。除此之外，应该没有类似分组或中文数字的格式。

I have an NSDecimal and need this as technical string, i.e. with no formatting in any way. Floating point should be a "." if there is any, and minus sign should just be a "-" if there is any. besides that, there should be no formatting going on like grouping or chinese numbers.

我通过SDK寻找2个小时，但似乎没有什么简单的。有没有解决方案？

I was looking for 2 hours through the SDK but it seems there is nothing simple to accomplish this. Are there solutions for this?

推荐答案

对于NSDecimal，你可以使用NSDecimalString指定的语言环境：

For NSDecimal, you can use NSDecimalString with a specified locale:

NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
NSString *decimalString =  NSDecimalString(&decimalValue, usLocale);
[usLocale release];

美国区域设置使用句点作为小数分隔符，没有千位分隔符，因此我相信

The U.S. locale uses a period for the decimal separator, and no thousands separator, so I believe that will get you the kind of formatting you're looking for.

正如其他人所指出的，对于NSDecimalNumber，您可以使用-descriptionWithLocale：方法与上述指定的US语言环境。这不会失去任何精确度。

As others have pointed out, for an NSDecimalNumber you can use the -descriptionWithLocale: method with the above-specified U.S. locale. This doesn't lose you any precision.
