Question

我一直在尝试制作一个可以暂时处理负数的批处理文件。我最好的猜测是在批处理文件中创建小“工程师”，在比较期间为每个数字添加1000，并在比较后将数字恢复为正常。我的计算机运行Windows 8，当我运行这个批处理文件时，即使在“工程师”完成其工作之后，它也会说Beta（应该等于-93）大于所有数字。我不知道如何解决这个问题。帮助

 @echo off
 :PRELOAD
 set alpha=0
 set beta=0
 set gamma=92
 :MONKEYWRENCH
 set /a beta=%beta% - 93
 echo Monkey Wrench
 :ENGINEERSTART
 set /a alpha=%alpha% + 1000
 set /a beta=%beta% + 1000
 set /a gamma=%gamma% + 1000
 :ECHOMONKEY1
 echo Alpha = %alpha%
 echo Beta = %beta%
 echo Gamma = %gamma%
 :COMPARE
 echo Start Comparison
 echo Alpha
 if '%alpha%' GEQ '%beta%' echo Alpha is greater than Beta
 if '%alpha%' LSS '%beta%' echo Alpha is lesser than Beta
 if '%alpha%' GEQ '%gamma%' echo Alpha is greater than Gamma
 if '%alpha%' LSS '%gamma%' echo Alpha is lesser than Gamma
 echo Beta
 if '%beta%' GEQ '%alpha%' echo Beta is greater than Alpha
 if '%beta%' LSS '%alpha%' echo Beta is lesser than Alpha
 if '%beta%' GEQ '%gamma%' echo Beta is greater than Gamma
 if '%beta%' LSS '%gamma%' echo Beta is lesser than Gamma
 echo Gamma
 if '%gamma%' GEQ '%alpha%' echo Gamma is greater than Alpha
 if '%gamma%' LSS '%alpha%' echo Gamma is lesser than Alpha
 if '%gamma%' GEQ '%beta%' echo Gamma is greater than Beta
 if '%gamma%' LSS '%beta%' echo Gamma is lesser than Beta
 echo End Comparison
 :ENGINEEREND
 set /a alpha=%alpha% - 1000
 set /a beta=%beta% - 1000
 set /a gamma=%gamma% - 1000
 :ECHOMONKEY2
 echo Alpha = %alpha%
 echo Beta = %beta%
 echo Gamma = %gamma%

删除所有引号。

'%var%'其中var = -83是字符串'-83' - 包括引号。然后批处理逐个字符地执行 ALPHABETICAL 比较，因此'123'小于'9'，因为1小于9
