Floating point division in a batch file

I need to do a floating-point division in a dos batch.

I didn\'t find a way to do it. Something like this :

SET /A Res=10/3

returns

Answer 1

I wrote a pure batch file specifically to do division. It takes the first number you input, and then divides it by the second one, and displays the result with as many decimal points as you specify.

Echo off
cls
if NOT "%3" == "" (
set n1=%1
set n2=%2
set max=%3
goto :begin
)

set counter=2
set n1=1
set n2=1
set ans=
:start
Echo.
Echo. 1 / 2
Echo.
Set /p N1= 1?
set /p N2= 2?
Set /p Max= Out how many Decimal Points?
:begin
set /a TmpAns=%N1%/%N2%
set ans=%TmpAns%.
:: Echo.%ans%.>Answer.txt

The answer put into the variable %Ans%. It can also be called with parameters. ("Divide.bat 50 27 5" would give you 50/27 out 5 decimal points.)
