楼上代码错了，不可以用替换的
不然所有71的数字都被你替换了

我把我的代码也贴到这，如果通用性有问题请告知
方法一：（用时0.25~0.30秒）

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%i in (LastNumberChange.txt) do set/a n+=1&set LastLine=$%%i$
for /f "delims=" %%i in (LastNumberChange.txt) do (
set/a m+=1
if %n% neq !m! call set "all=!all!%%i&echo."
)

:start
set FirstNumber=%LastLine:~,1%
set "all1=!all1!%FirstNumber%"
set LastLine=%LastLine:~1%
echo %LastLine%|findstr "[0-9]" >nul&&goto :start
:all1
set /a t+=1
call set LastOne=%%all1:~-!t!%%
set/a x=LastOne*1
if "%LastOne%"=="%x%" goto :all1
set/a LastOne=%LastOne:~1%*7
set /a t-=1
set xlm=!all1:~,-%t%!
Set "Sum=%all%%xlm%%LastOne%%LastLine%"
echo %Sum:$=%
pause

方法二：（用时0.02~0.05秒）

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%i in (LastNumberChange.txt) do set/a n+=1&set LastLine=$%%i$
for /f "delims=" %%i in (LastNumberChange.txt) do (
set/a m+=1
if %n% neq !m! call set "all=!all!%%i&echo."
)
:LastOne
set/a x+=1
call set LastOne=%%LastLine:~-!x!,1%%
set /a Mult=%LastOne%*1
if not "%Mult%"=="%LastOne%" goto :LastOne
set/a x-=1
call set Front=%%LastLine:~,-%x%%%
call set Last=%%LastLine:~-%x%%%
:Middle
set/a x1+=1
call set LastOne1=%%Front:~-!x1!%%
set /a Mult1=%LastOne1%*1
if "%Mult1%"=="%LastOne1%" goto :Middle
set/a Middle=%LastOne1:~1%*7
set/a x1-=1
call set Front=%%Front:~,-%x1%%%
set "Sum=%all%%Front%%Middle%%Last%"
echo %Sum:$=%
pause

楼上代码还是有问题啊
如果最后一行的数值是下面的三种形式就不行了

4##59.71#3715.45##71
复制代码

71##
复制代码

71
