问题描述

我的数字类型为double。
double a = 12.00
我必须通过删除.00使其变为12

I have number of type double. double a = 12.00 I have to make it as 12 by removing .00

请帮助我

推荐答案

12 和 12.00 完全相同表示为 double 值。您是要以 double 还是其他价格结尾？ （例如，如果您确信该值将在正确的范围内，并且您想要的是截断效果，则可以强制转换为 int 。）

Well 12 and 12.00 have exactly the same representation as double values. Are you trying to end up with a double or something else? (For example, you could cast to int, if you were convinced the value would be in the right range, and if the truncation effect is what you want.)

您可能也想看看这些方法：

You might want to look at these methods too:

• Math.Floor


• Math.Ceiling


• Math.Round （具有处理中点的方式）


• Math.Truncate

• Math.Floor
• Math.Ceiling
• Math.Round (with variations for how to handle midpoints)
• Math.Truncate
