如何在 Java 中将整数转换为浮点数?

How can I convert integer into float in Java?(如何在 Java 中将整数转换为浮点数?)

问题描述

我有两个整数 x 和 y.我需要计算 x/y 作为结果，我想获得浮动.例如，作为 3/2 的结果，我想要 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.你能帮我解决这个问题吗?

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?

推荐答案

您只需要将至少一个操作数强制转换为浮点数:

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

float z = (float) x / y;

或

float z = x / (float) y;

或(不必要的)

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