漂浮或翻番黑莓？ [英] Float or double on Blackberry?

问题描述

您可以使用双或漂浮在黑莓？

Can you use double or float on Blackberry?

如果是这样，在OS版本或硬件模式？

If so, in which OS version or hardware model?

编辑：我相信，我来到这里的答案，但随后<一个href=\"http://stackoverflow.com/questions/5964762/why-is-neither-float-nor-double-working-on-blackberry\">something否则一定是问题。

I believe the answers I get here, but then something else must be the problem.

推荐答案

显然浮点的不工作的黑莓上的某些版本;见注释。

Apparently floating point doesn't work on some versions of Blackberry; see the comments.

弓，如果J2ME设备实现CLDC 1.0轮廓，不需要制造商包括用于浮点运算的平台支持：见

Bow, if a J2ME device implements the CLDC 1.0 profile, the manufacturer is not required to include support for floating point arithmetic in the platform: see

http://cmer.cis.uoguelph.ca/cs1cs3/slides.ppt

在CLDC 1.1，支持浮点是强制性的。

In CLDC 1.1, floating point support is mandatory.

在对其他问题的意见，你说黑莓是CLDC 1.1。

In comments on other questions, you say that Blackberry is CLDC 1.1.

如果你的黑莓手机的浮点支持不工作，它真的声称实施CLDC 1.1，那么这就是无论是在执行平台或错误的构建工具链，或者用你的方式有问题的使用的工具链。 （我不开发J2ME的东西，所以我不能更具体。）

If your Blackberry's floating point support doesn't work and it really claims to implement CLDC 1.1, then that's either a bug in the execution platform or the build tool-chain, or a problem with the way you are using the tool-chain. (I don't develop J2ME stuff, so I can't be more specific.)
