Don't you simply want to sometimes do math without having to open calculator? By simply typing it somewhere and have the result real quick?
Of course, you can do it on your phone, but what if you could do it with Start - Run?
1. Create a bat file using the code below (give it any name you want)
@echo off
setlocal
:: Check for input
if "%~1"=="" (
echo Usage: calc 3365/5
pause
exit /b
)
:: Join all parameters into one expression
set "expr=%~1"
:loop
shift
if "%~1"=="" goto done
set "expr=%expr% %~1"
goto loop
:done
:: Use PowerShell to evaluate
for /f "delims=" %%A in ('powershell -command "try {[math]::Round((%expr%), 4)} catch { 'Error' }"') do set "result=%%A"
:: Show result
echo %expr% = %result%
echo %result%|clip
msg * %expr% = %result%
endlocal |
2. Save the file wherever you want
- I saved it in: D:\Custom APPS by Mrrrr
- I named it: do math in start-run.bat
3. Open the Windows Registry and create an App Path entry
- Win+R, type regedit, press Enter
- navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
- right click the App Paths folder, New > Key
- name the key: c.exe
- you should now have: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\c.exe
4. In the folder where you saved you bat file, right click the bat file and select Copy as path
- I got: "D:\Custom APPS by Mrrrr\do math in start-run.bat"
5. In regedit, inside key c.exe, under (Default) enter the full path to your bat file that you previously copied to clipboard
- now you can close the registry editor
6. Press Win+R to start the Run dialog, then type: c 365/5+123-321/3 and press Enter
- you will get a MsgBox displaying you the math you typed and the result
- in this example the MsgBox will contain: 365/5+123-321/3 = 89
- let's verify that: 365/5 = 73+123 = 196-107 = 89
