百分数表示百分数(百),即百分数与100之比。百分数的符号为%。我们通常会计算获得的商标,投资回报率等百分比。该百分比也可以超过100%。
例如,假设我们有总数和一部分。所以我们说那一部分占总数的百分之几,应计算为-
percentage = ( part / total ) × 100
1. Collect values for part and total 2. Apply formula { percentage = ( part / total ) × 100 } 3. Display percentage
import java.util.Scanner; public class Percentage { public static void main(String args[]){ float percentage; float total_marks; float scored; Scanner sc = new Scanner(System.in); System.out.println("Enter your marks ::"); scored = sc.nextFloat(); System.out.println("Enter total marks ::"); total_marks = sc.nextFloat(); percentage = (float)((scored / total_marks) * 100); System.out.println("Percentage ::"+ percentage); } }
输出结果
Enter your marks :: 500 Enter total marks :: 600 Percentage ::83.33333
