如何使用 Java 将 float 转换为 int

2022-01-09 00:00:00 floating-point int java

我使用以下行将 float 转换为 int,但它并不像我想要的那样准确:

I used the following line to convert float to int, but it's not as accurate as I'd like:

 float a=8.61f;
 int b;

 b=(int)a;

结果是:8(应该是9)

a = -7.65f时,结果为:-7(应该是-8)

When a = -7.65f, the result is : -7 (It should be -8)

最好的方法是什么?

推荐答案

使用 Math.round() 会将浮点数四舍五入到最接近的整数.

Using Math.round() will round the float to the nearest integer.
