mathservice.java

JAVA实现的一个能够做多个数学功能的client-server程序。

public class MathService {
	public double sqrt(double num){
		return Math.sqrt(num);
	}
	
	public double sin(double num){
		return Math.sin(num);
	}
	
	public double cos(double num){
		return Math.cos(num);
	}
	
	public double tan(double num){
		return Math.tan(num);
	}
	
	public double log(double num){
		return Math.log(num);
	}
	
	public boolean prime(int num){
		if(num == 1){
			return false;
		}
		for(int i=2; i<=Math.sqrt((double)num); i++){
			if(num%i==0){
				return false;
			}
		}
		return true;
	}
}
