如何将整数转换为Java中的float？ [英] How can I convert integer into float in Java?

问题描述

我有两个整数 x 和 y 。我需要计算 x / y 作为结果，我想浮动。例如，作为 3/2 的结果，我希望有1.5。我认为最简单（或唯一）的方法是将 x 和 y 转换为浮点类型。不幸的是，我找不到一个简单的方法来做到这一点。你可以帮我一下吗？

您只需强制转换

  float z =（float）x / y; 
  

或

  float z = x /（float）y; 
  

或（不必要的）

pre > float z =（float）x /（float）y;


I have two integers x and y. I need to calculate x/y and as outcome I would like to get float. For example as an outcome of 3/2 I would like to have 1.5. I thought that easiest (or the only) way to do it is to convert x and y into float type. Unfortunately, I cannot find an easy way to do it. Could you please help me with that?

解决方案

You just need to cast at least one of the operands to a float:

float z = (float) x / y;

or

float z = x / (float) y;

or (unnecessary)

float z = (float) x / (float) y;
