Topic description :
Given a float base of type double and an integer exponent of type int. Find the exponent power of base.
Problem- solving idea:
through loop iteration, realize the multiplication of n numbers, don't forget the case of negative numbers
代码如下：
public class Solution { public double Power(double base, int exponent) { double a=1.000000; if(exponent>=0){ for(int i=0;i<exponent;i++){ a=a*base; }
}else{ for(int i=0;i>exponent;i–){ a=a*base; } a=1/a; } return a; } }
operation result:
