Strongly learn from the各位 upstairs. （注：原句“强烈的向楼上各位学习。”中“强烈的”表述有误，应为“强烈地”，正确翻译为“Strongly learn from the各位 upstairs.” 但根据要求要保留原文错误的话就按错误的翻译，不过更准确的应该是“Strongly learn from everyone upstairs.”）

Hexadecimal to decimal: There is a simpler way. @echo off set /p b=Please enter a hexadecimal number: set /a a=0x%b% echo %a% pause

Hexadecimal to decimal. I know a very simple method, which I learned from the post about getting ASCII codes I saw yesterday... set/p num= set/a a=0x%num% echo %a% pause

rem Three different data inputs, but all will be output in decimal. rem Decimal set /a 123 rem Octal set /a 012 rem Hexadecimal set /a 0xa

The conversion between number bases has actually been discussed before.

It seems that there was one posted before. Adding a variable can realize decimal to any base conversion.
