C＃编译器数量文字 [英] C# compiler number literals

问题描述

有谁知道C＃编译器数量文字修饰的完整列表？

在默认情况下，宣布0使一个Int32和'0.0'使它成为双师型。我可以用文字修饰'F'末，以确保一些被视为'单'代替。例如像这样...

  VAR X = 0; // x是的Int32
变种Y = 0F; // y是单
 

什么是其他修饰符可以使用吗？是否有一个强制为双，小数，UInt32的？我尝试使用Google的这一点，但无法找到任何东西。也许我的术语是错误的，那么这可以解释为什么我来了空白。任何帮助非常AP preciated。

解决方案

 变种Y = 0F; // f是单
变种Z = 0D; // z是双
变种R =0米; // r是小数
VAR I = 0U; //我为unsigned int
变种J = 0L; // j是长（注：为清楚起见资本L）
VAR K = 0UL; // k是无符号长（为清楚起见注资L）
 

从 C＃规范2.4.4.2 整数文字2.4.4.3与真正的文字。需注意，L和UL是pferred，而不是他们的清晰度小写变种$ P $所推荐的乔恩斯基特

Does anyone know the full list of C# compiler number literal modifiers?

By default declaring '0' makes it an Int32 and '0.0' makes it a 'Double'. I can use the literal modifier 'f' at the end to ensure something is treated as a 'Single' instead. For example like this...

var x = 0;    // x is Int32
var y = 0f;   // y is Single

What are the other modifiers I can use? Is there one for forcing to Double, Decimal, UInt32? I tried googling for this but could not find anything. Maybe my terminology is wrong and so that explains why I am coming up blank. Any help much appreciated.

解决方案

var y = 0f; // f is single
var z = 0d; // z is double
var r = 0m; // r is decimal
var i = 0U; // i is unsigned int
var j = 0L; // j is long (note capital L for clarity)
var k = 0UL; // k is unsigned long (note capital L for clarity)

From the C# specification 2.4.4.2 Integer literals and 2.4.4.3 Real literals. Take note that L and UL are preferred as opposed to their lowercase variants for clarity as recommended by Jon Skeet.
