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. 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

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.
简单!简单!再简单!

The code at that time
@echo off&setlocal enabledelayedexpansion

set/p a=Please enter the decimal number to convert:

set aa=%a%

set/p b=Please enter the base to convert to:

set str=0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

:hex

    set/a m=!a!/!b!

    set/a n=!a!%%!b!

    set n=!str:~%n%,1!

    set h=!n!!h!

    if !m! geq !b! set a=!m! &goto hex

    set m=!str:~%m%,1!

    echo !aa! in base !b! is !m!!h!
