问题 I need roundoff function in J2ME. Math.round() does not seem to exist. Please provide some assistance! 回答1: Or you can use another approach: float value; int base; //base to round int round_down=(int )((int )(value/base))*base; int round_up=(int )((int )(value/base+0.5))*base; 回答2: Math.ceil() or Math.floor() probably but these again are available only for CLDC 1.1 :) 来源： https://stackoverflow.com/questions/4930598/is-there-a-round-off-function-in-j2me

问题 I developed some small applications for the Nokia 6131 that supported NFC. The SDK was special for this device, and it implemented the JSR 257. Now, I see different mobile platforms with proprietary SDKs, each one proposing different features (Android ICS, Meego, iOS). I would like to know which platform still support JSR 257?

问题 There are at least two ways that I know of to write a Symbian application: 1. J2ME 2. A native application. My question is, does the SDK/API for either of those methods (or any other method) grant me (at least) read-only access to contact information (names/numbers/etc) on the phone itself?
