C＃在小数点中移动小数点 [英] C# move decimal point in a double

问题描述

我想将格式为xx.xxxx的滑块转换为双倍格式为xxxxxx.xx的双倍格式。





示例如果收到：15.678934我想把它传入：156789.34

我在几个地方检查过但我只找到要在之前或之后舍入或添加ceros的公式

 mydouble.ToString（  ######。##，CultureInfo.InvariantCulture））; 
 
 
 mydouble.ToString（  0000：00.00， CultureInfo.InvariantCulture））; 

我还检查了starndart和自定义字符串格式，但显然没有任何东西适合我的目标：http://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs .110）.aspx [ ^ ]



请帮忙吗？

解决方案

试试这个：

  double  d =  12 。< span class =code-digit> 345678 ; 
 Console.WriteLine（  {0,8：000000.00}，d）; 
 Console.WriteLine（  {0}，d.ToString（  000000.00））; 
 

我不知道我在想什么！最近我不得不做很多解析和转换的东西，我没有意识到，对于这种情况，解决方案是简单的数学!!

  double  dconverted = mydouble * 10000; 
 d.tostring（  ######。##）; 

I want to transform a double get it from a slider with format "xx.xxxx" into a double with next format "xxxxxx.xx".


Example if receive: 15.678934 I want to convet it in: 156789.34
I checked in several places but I only find formulas to round or add ceros before or after like

mydouble.ToString("######.##", CultureInfo.InvariantCulture) );


mydouble.ToString("0000:00.00", CultureInfo.InvariantCulture) );

Also I checked the starndart and custom string formats but apparently nothing fits with my objetive: http://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.110).aspx[^]

Any help please ?

解决方案

Try this:

double d = 12.345678;
Console.WriteLine("{0,8:000000.00}", d);
Console.WriteLine("{0}", d.ToString("000000.00"));

I don't know what I was thinking ! Lately I had to do many parsing and conversions stuff that I didn't realize that for this case the solution were simple maths!!

double dconverted=mydouble*10000; 
d.tostring("######.##");
