简单percentange计算

Question

请看看下面的代码，并告诉我，为什么skillPercentange始终为零：

NSInteger skillPercentange; 
skillPercentange=totalCorrectAns * reloader/100; 

Answer 1

我并不确切地知道你想要做什么，但我会尽力给你看演示：

int allQuestions = 50; 
int correctAnswers = 25; 
float precentage = (100 * correctAnswers)/allQuestions; 
NSLog("%i of %i questions answered correctly. That are %.1f percent!",correctAnswers,allQuestions,precentage); 

输出： “50个问题25回答正确即50.0％的！”

Answer 2

NSInteger skillPercentange; 
skillPercentange = 100 * totalCorrectAns/reloader; 

Answer 3

float skillPercentange; 
skillPercentange=(totalCorrectAns * reloader)/100; 

或

skillPercentange= totalCorrectAns * (reloader/100); 

根据什么是你的公式。

NSLog(@"skillPercentange=0.1f",skillPercentange);
