一个整数值的千位分隔符 [英] Thousands separator of an integer value

问题描述

让我们说我有这在我的批处理文件：

Let's say I have this in my batch file:

set var1=12345

和我想在第一个变量的（VAR1）添加逗号并将其保存到另一个变量的（VAR2）

And I want to add commas in the first variable (var1) and save it to another variable (var2).

这意味着，第二个变量的（VAR2）应该有这个值： 12345

That means that the second variable (var2) should have this value: 12,345.

因此​​，如果第一个变量（VAR1）有这个价值：123456789，第二个的（VAR2）值必须123,456,789

So If the first variable (var1) had this value: 123456789, the second one's (var2) value has to be 123,456,789.

任何想法？

编辑：

我不希望PowerShell命令，因为没有为我工作。
请写的没有的PowerShell。

I don't want PowerShell commands because the don't work for me. Please write without PowerShell.

推荐答案

另外一个！

@echo off
setlocal EnableDelayedExpansion

set "var1=%1"

echo First variable: %var1%


set "var2="
set "sign="
if "%var1:~0,1%" equ "-" set "sign=-" & set "var1=%var1:~1%"
for /L %%i in (1,1,4) do if defined var1 (
   set "var2=,!var1:~-3!!var2!"
   set "var1=!var1:~0,-3!"
)
set "var2=%sign%%var2:~1%


echo Second variable: %var2%

如果你想增加的位数，只是增加组数在为命令值大于4。

If you want to increase the number of digits, just increase the number of groups in the for command to a value greater than 4.
