我正在使用Unity制作一个＆＃34;增量游戏＆＃34;也被称为＆＃34;空闲游戏＆＃34;而我正在尝试格式化大数字。例如，当gold说1000或更多时，它将显示为Gold: 1k而不是Gold: 1000。
using UnityEngine;
using System.Collections;
public class Click : MonoBehaviour {
public UnityEngine.UI.Text GoldDisplay;
public UnityEngine.UI.Text GPC;
public double gold = 0.0;
public int gpc = 1;
void Update(){
GoldDisplay.text = "Gold: " + gold.ToString ("#,#");
//Following is attempt at changing 10,000,000 to 10.0M
if (gold >= 10000000) {
GoldDisplay.text = "Gold: " + gold.ToString ("#,#M");
}
GPC.text = "GPC: " + gpc;
}
public void Clicked(){
gold += gpc;
}
}
我在网上搜索时尝试了其他示例，这是gold.ToString ("#,#");来自的地方，但是没有一个有效。

轻微重构：
public static string KMBMaker( double num )
{
double numStr;
string suffix;
if( num < 1000d )
{
numStr = num;
suffix = "";
}
else if( num < 1000000d )
{
numStr = num/1000d;
suffix = "K";
}
else if( num < 1000000000d )
{
numStr = num/1000000d;
suffix = "M";
}
else
{
numStr = num/1000000000d;
suffix = "B";
}
return numStr.ToString() + suffix;
}
使用：
GoldDisplay.text = KMBMaker(gold);

我不认为有一种内置方法，所以我只是通过写自己的方式重新发明轮子，但这应该是我可能会这样做
using System;
using System.Collections.Generic;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
for (double i = 500d; i < 5e23; i *= 100d)
{
Console.WriteLine(i.ToMyNumber());
}
Console.Read();
}
}
public static class helper
{
private static readonly List<string> myNum;
static helper()
{
myNum = new List<string>();
myNum.Add("");
myNum.Add("kilo");
myNum.Add("mill");
myNum.Add("bill");
myNum.Add("tril");
myNum.Add("quad");
myNum.Add("quin");
myNum.Add("sext");
// ....
}
public static string ToMyNumber(this double value)
{
string initValue = value.ToString();
int num = 0;
while (value >= 1000d)
{
num++;
value /= 1000d;
}
return string.Format("{0} {1} ({2})", value, myNum[num], initValue);
}
}
}
打印此
500 (500)
50 kilo (50000)
5 mill (5000000)
500 mill (500000000)
50 bill (50000000000)
5 tril (5000000000000)
500 tril (500000000000000)
50 quad (5E+16)
5 quin (5E+18)
500 quin (5E+20)
50 sext (5E+22)

我在我的项目中使用此方法，您也可以使用。也许有更好的方法，我不知道。
public void KMBMaker( Text txt, double num )
{
if( num < 1000 )
{
double numStr = num;
txt.text = numStr.ToString() + "";
}
else if( num < 1000000 )
{
double numStr = num/1000;
txt.text = numStr.ToString() + "K";
}
else if( num < 1000000000 )
{
double numStr = num/1000000;
txt.text = numStr.ToString() + "M";
}
else
{
double numStr = num/1000000000;
txt.text = numStr.ToString() + "B";
}
}
并在此更新中使用此方法。
void Update()
{
KMBMaker( GoldDisplay.text, gold );
}

我用这个：
private static List<string> nFormat= new List<string>();
void Awake()
{
nFormat.Add("");
nFormat.Add("K");
nFormat.Add("M");
nFormat.Add("B");
//...
}
public static string Double2dec(double value)
{
int num = 0;
while (value >= 1000d)
{
num++;
value /= 1000d;
}
return value.ToString("F2") + nFormat[num];
}

我尝试了这里给出的一些解决方案，但由于需要写下从 K 到 NoNod 的所有缩写的努力而推迟，所以我写了这个 - 尽管我还没有尝试过它是否会极大地影响性能（尽管它似乎和使用科学记数法一样流畅）。
using System;
//System.Numerics necessary for us of BigInteger only - alternatively use double (which might be faster, but more inaccurate
using System.Numerics;

*/
public enum NumberFormat
{
Scientific,
Abbreviation
}
public static string FormatNumber(BigInteger number, NumberFormat format = NumberFormat.Scientific)
{
if (format == NumberFormat.Scientific)
return ScientificFomat(number);
else
return AbbreviationFormat(number);
}
public static string ScientificFomat(BigInteger number)
{
if (number < 1000)
//if number smaller than 1,000, don't use special format
return number.ToString("#.##0");

//return number as scientific notation with 1 place before and 3 places after decimal point
return number.ToString("e3");
}
public static string AbbreviationFormat(BigInteger number)
{
if (number < 1000)
//if number smaller than 1,000, don't use special format

}
}
//since the number string is at this point definitly more than 3 places long, use the remainder to set the decimal point
string numberstr = number.ToString().Substring(0, 4).Insert(remainder + 1, ",");
//put the number with decimal point together with the appendix | example: 123,456,789,012,345,678,901,234,567,890,123,456,789,012 -> 123,4DDc
return numberstr + appendix;
}
}
}
}
希望这会有所帮助。
