稍微美化了一点:

@echo off
title Delay divider
cd /d %~dp0

:start
cls
echo.
echo The script will divide all the numbers by 100.
echo Please put all the number segments to be divided in 1.txt.(Only integers are supported)
echo Then enter start to start.
echo All the results will be in 2.txt
echo.
set /p "input=Please enter start to start:"
if /i "%input%"=="start" goto start0
cls
echo ERROR!
echo Please push any key to restart.
pause>nul
goto start

:start0
cls
echo loading...
setlocal EnableDelayedExpansion
set "inputFile=1.txt"
set "outputFile=2.txt"
if exist "%outputFile%" del "%outputFile%"
for /f %%a in ('type "%inputFile%"') do (
    set /a "result=%%a/100"
    echo !result!>>"%outputFile%"
)
echo Done!
echo Please push any key to restart.
call 2.txt
pause>nul
goto start

setlocal EnableDelayedExpansion
set "inputFile=1.txt"
set "outputFile=2.txt"

if exist "%outputFile%" del "%outputFile%"

for /f %%a in ('type "%inputFile%"') do (

echo Done!

pause

忘记加setlocal EnableDelayedExpansion力

@echo off

set inputFile=1.txt
set outputFile=2.txt

if exist "%outputFile%" del "%outputFile%"

for /f %%a in ('type "%inputFile%"') do (
    set /a "result=%%a/100"
    echo !result!>>"%outputFile%"
)

echo Done!

pause

脚本会首先将 1.txt 中的每一行内容读取到 result 变量中，并将其除以 100 得到计算结果。然后将每次循环得到的 result 变量值追加到 2.txt 文件中。如果 2.txt 已经存在，则在执行前将其删除，以免原来的内容对结果产生影响。

ps:不支持处理浮点数，只能处理整数,请不要包含任何空格或其他无关字符。
