[数值计算] 【已解决】BAT脚本kytes转换mb计算时超过32精确度

赖渊

我使用了普通的bat除法命令，然而会出现数值过大导致无法计算。
请问有大佬给个好点子吗？

计算函数部分用的是这个，但是感觉除法这个帖子的函数太复杂了....

bat脚本打算是用来删除班上电脑sewwo教学系列程序的日志淤积文件用的（大概2G左右）
路径还没有写入，这个无视就好。。。。

麻烦各位了。。。

修改成

for /f %%i in ('powershell -c "%dx1% /1024 /1024"') do (
set "q=%%i"
echo %q%
复制代码

就不执行下面的运算函数而是直接退出
我尝试添加

pause > nul 
复制代码

来看看运行过程也都是直接退出。。。。
