我正在开发一个简单的j2me应用程序.我需要像在Java中的pow(double num1, double num2)中那样获得数字的幂. 但是据我所知，j2me不支持此pow()方法. 任何有用的选项，不胜感激.

I'm developing a simple j2me application. There I need to get the power of a number as like as in the pow(double num1, double num2) in java. But as I got to know, j2me doesn't support to this pow() method. Any helpful option is appreciated.

推荐答案

public double pow(double num1, double num2) {
  double result = 1;
  for (int i = 0; i < num2; i++)
    result *= num1;
  return result;
}
