摘要
使用J2ME手机开发工程测量软件过程中,由于CLDC1.1的局限,提供的数值计算函数并不充分,特别是缺少关键的乘幂计算函数。推导乘幂计算的数学算法,给出按此方法计算的实例。在J2ME手机开发中通过建立roadMath类,完成乘幂计算的JAVA编程实现,同时扩充CLDC1.1的数学计算函数。
While developing the engineering survey software based on J2ME mobile phone, we find that numerical computation functions in CLDC1.1 are not sufficient, especially the lack of the power computation function. The mathematic arithmetic for power computation is deducted, and a power computation example is shown for understanding easily. By creating a Class of roadMath, not only the power arithmetic is realized by JAVA programming, but also the mathematic computation functions in CLDC1.1 are enlarged.
