Question

好吧所以我一直在处理一个批处理文件，它将十进制十进制值转换为十六进制，但是我无法得到for循环和if语句，我看起来似乎只是给了我错误的信息这是我的代码。谢谢你的回复

Answer 1

假设您要将十六进制转换为十进制数字：

为什么不单独使用set /A来完成这项工作呢？ set /A能够在以0x为前缀时将十六进制转换为十进制数。有关详细信息，请参阅set /? 下面的行在DEC中存储十进制数，假设HEX包含十六进制数字：

set /A DEC=0x%HEX%

以下脚本会提示用户输入十六进制。编号并显示其十进制表示：

@echo off
:LOOP
set "HEX="
set /P "HEX=Enter a hexadecimal number (up to 8 digits): "
if not defined HEX goto :EOF
set /A DEC=0x%HEX%
echo The decimal representation of %HEX% is %DEC%.
goto :LOOP

请注意，十六进制数限制为8位（32位），并将其解释为有符号值。

假设您要将十进制转换为十六进制数字：

有一个名为=ExitCode的无证built-in environment variable，它包含当前返回或退出代码的十六进制字符代码（ASCII）（通常是ErrorLevel）。下面的行在HEX中存储十六进制数字，假设DEC包含十进制数字：

cmd /C exit %DEC%
set "HEX=%=ExitCode%"

以下脚本会提示用户输入十进制数字并显示其十六进制数。表示：

@echo off
:LOOP
set "DEC="
set /P "DEC=Enter a decimal number (signed 32-bit integer): "
if not defined DEC goto :EOF
cmd /C exit %DEC%
set "HEX=%=ExitCode%"
for /F "tokens=* delims=0" %%Z in ("%HEX%") do set "HEX=%%Z"
if not defined HEX set "HEX=0"
echo The hexadecimal representation of %DEC% is %HEX%.
goto :LOOP

Answer 2

Phew - 代码很多。这有点短：

@echo off
setlocal enabledelayedexpansion
set "hex=0123456789ABCDEF"
set /p INPUT=Enter a number (0-255):
set /a high=%INPUT% / 16
set /a low=%INPUT% %% 16
echo in hexadecimal %INPUT% = !hex:~%high%,1! !hex:~%low%,1!

Answer 3

使用.bat扩展程序保存此内容：

@if (@x)==(@y) @end /***** jscript comment ******
     @echo off

     cscript //E:JScript //nologo "%~f0" %*
     exit /b 0

 @if (@x)==(@y) @end ******  end comment *********/

 var args=WScript.Arguments;
 var number=args.Item(0);

 WScript.Echo(parseInt(number,16));

并像

一样使用它

for /f %%# in ('hexToDec.bat 10E4') do set "decimalNumber=%%#"
echo %decimalNumber%
