物体做抛物线运动是游戏中基本运动物理模型之一！ 在PC游戏中可以由重力公式 轻易模拟，但在手机游戏中 ，由于多数手机不支持浮点运算 因此不能用 sin ，cos，　来分解初速度。　所以只能用近似模拟的方法！　我所采用的是：先放大后缩小的模拟方式，并且为了更精确加入了一定的偏移量。-objects do parabolic movement is the basic game campaign physical model one! The PC game can be easily simula

Descr iption Scientific calculator. Allows to perform caclulation with high precicion and implements most populatr mathematical functions: sin, cos, tan, asin, acon, atan, exp, log, sqr, floor and ceil. Also it make it possible to define your ow

j2me midp1.0没有实现浮点运算，这个实现了midp1.0上的浮点运算。-j2me midp1.0 not achieved floating-point operations, the realization of the midp1.0 on the floating-point operations.

很多时候都能用到的，主要解决CLDC1.0中不支持浮点数的问题，做J2ME开发的朋友应该用得到。-A lot of moment are could not CLDC1.0, mainly to solve the problem, support floating-point J2ME development friends should do with get.
