提问by Jared
How does one convert from an int or a decimal to a float in C#?
如何在 C# 中将整数或十进制数转换为浮点数？
I need to use a float for a third-party control, but I don't use them in my code, and I'm not sure how to end up with a float.
我需要为第三方控件使用浮点数，但我没有在我的代码中使用它们，而且我不确定如何以浮点数结束。

You can just do a cast
你可以做一个演员
int val1 = 1;
float val2 = (float)val1;
or
或者
decimal val3 = 3;
float val4 = (float)val3;

It is just:
它只是：
float f = (float)6;
回答by Chris Pietschmann
The same as an int:
与 int 相同：
float f = 6;
Also here's how to programmatically convert from an int to a float, and a single in C# is the same as a float:
此外，这里还介绍了如何以编程方式从 int 转换为 float，C# 中的 single 与 float 相同：
int i = 8;
float f = Convert.ToSingle(i);
Or you can just cast an int to a float:
或者您可以将 int 转换为浮点数：
float f = (float)i;
回答by Dave the Troll
You don't even need to cast, it is implicit.
您甚至不需要强制转换，它是隐式的。
int i = 3;
float f = i;
