Objective-C从数学计算中得到0

Question

int desiredQuality = call.arguments[@"desiredQuality"]; //BETWEEN 0 AND 1602
float calculatedQuality = desiredQuality/1602; //RETURNS 0

日志：

APP: this is the desiredQuality: 802
APP: this is the calculatedQuality: 0.000000

我尝试将calculateQuality更改为int或double，但我得到相同的结果。我做错了什么？

Answer 1

这是int师

float calculatedQuality = desiredQuality/1602; //RETURNS 0

如果数字小于1602，它将返回0，您需要将其转换为

float calculatedQuality = desiredQuality/1602.0; //RETURNS 0.5
