C#字符串以f浮动 [英] C# String to float with f

问题描述

顺便说一句:xposs是从服务器接收的，所以我不能只说它是浮点数，我需要将其转换为后面带有0.0f的浮点数:

BTW: the xposs is recieved from a server so i cant just say its a float, i need it converted to a float with 0.0f behind:

xposs = "951.9791"

xspawn = float.Parse(yposs);

这只返回浮点数951.9791，但我要951.9791f

this just returns 951.9791 in a float but i want 951.9791f

我也尝试过:

xposs = "951.9791"

xspawn = float.Parse(yposs) + 0.0f;

这仍然行不通.

我需要将其设置为0.0f格式，因为我在Vector3()中使用了它，但是没有f似乎没有用(很好，但是坐标完全错误，如果我在它之后手动按f有效.)

I need it to be 0.0f format becaouse i use it in a Vector3(), and not having the f does not seem to work (well it works but the cordinates are totally wrong, and if i manually press f after it works.)

推荐答案

f后缀仅适用于代码中的文字.它用于将文字值表示为float.如果不存在后缀-文字值将为double

f postfix is applied only to literals in code. It is used to denote literal values as float. If no postfix is present - literal value will be of type double

您可以将float.Parse(stringValue)的结果作为Unity 3d中的构造函数参数传递给Vector3和Vector2 接下来的代码创建一个Vector3对象，其x y z等于在字符串

you can pass the result of float.Parse(stringValue) into Vector3 and Vector2 as constructor arguments in Unity 3d The next code create a Vector3 object with x y z equal to value set in string

string sideSize = "12.5";
float vectorSide = float.Parse(sideSize, CultureInfo.InvariantCulture);
Vector3 resultVector = new Vector3(vectorSide, vectorSide, vectorSide); //create vector3 with x = y = z = 12.5
