Question

I have this:

@echo off
setlocal ENABLEDELAYEDEXPANSION
set bla="-666"
set zzz="333"
if !zzz! LSS !bla! echo lesser
pause

Gives me “lesser” which is wrong. I know this is because of the ASCII values. But what is the way around to compare them as if they are numbers?

EDIT:

Some more codes:

set mn=99999
for /f "tokens=1-9" %%a in (%%g) do (
set zzz=%%d
)
if "!zzz!" LSS "!mn!" set mn=!zzz!

None of the answers below gave me the correct result so far…

Answer 1

This works for me, removing the quotes and then comparing.

@echo off
setlocal ENABLEDELAYEDEXPANSION
set bla="-666"
set zzz="333"
for %%a in (!bla!) do set /a bla=%%~a+0
for %%a in (!zzz!) do set /a zzz=%%~a+0
echo !bla! !zzz!
if !bla! LSS !zzz! (
    echo lesser
) else (
    echo greater
)   
pause
