Calculation in a .bat script
Good evening everyone,
I would like to perform calculations in a .bat script. Is that feasible? If so, how can I initialize a variable and increment it? Thank you in advance for your help.

Hello,
you don't even need to initialize your variables, you just do it like this:@echo off set /a variable=(2*5)/2 echo The result is %variable% pause
You can also prioritize your calculations using parentheses.

Good luck

no, you cannot
the only way is to integrate GNU tools like expr (unix command) on the machines where the script will run
expr $TOTO + 1 to increment the value of TOTO-

I dig it up, but to calculate a power in batch we do it like this We create the function !!!! )
Nothing is impossible, your inability to solve a problem does not mean that it's unfeasible!
setlocal EnableDelayedExpansion
set /P taille_mdp="the power value to be applied:"
echo password length=!taille_mdp!
set /P var_taille="enter the number to calculate"
cls
:power
for /L %%a in (1,1,!taille_mdp!) do (
set power=!power!*!var_taille!
)
::count number of digits
:count_number_combination
set /A count_power+=1
set var_power=!power:~%count_power%,1!
if not "!var_power!"=="" goto count_number_combination
set /A power_n=!power:~1,%count_power%!
echo !power_n!
pause
exit -
ContributorOff-topic since this code always returns an integer... I was also talking about calculations with decimal numbers (regardless of the operator), and the batch cannot do that natively! I confirm what I'm saying!
So before talking about the probable inability of others, make sure to read the problem well before giving a solution ^^
No hard feelings :) -
