如何一串数字右向左添加分号
各位好,好像此前有垃圾信息么?请教下,就是rmb

从右向左隔三个数字添加","是正确的

1. set pax=12345678
   
2. 123
   
3. 1,234
   
4. 12,345
   
5. 12,345,678
   

复制代码

我弄的从左向右隔三个数字","且if是删除后面空的","不正确

1. set pax=12345678
   
2. 123,4
   
3. 123,45
   
4. 123,456
   
5. 123,456,7
   
6. set s=%pax%
   
7. set pax=!s:~0,3!,!s:~3,3!,!s:~6,3!,!s:~9,3!,!s:~12,3!
   
8. if "%pax:~-1%" equ "," set "pax=%pax:~,-1%"
   
9. if "%pax:~-1%" equ "," set "pax=%pax:~,-1%"
   
10. if "%pax:~-1%" equ "," set "pax=%pax:~,-1%"

这可以从右向左,但查询变量有几个,比下面,好选择选择,如何知道变量多少个?
set pax=12345678   8个
set pax=123488      6个

xczxczxcz

8%%3余2，从第2个后开如加；6%%3整除，从第3个后开始加；
