The below set variable outputs the sum of 6 and 2. This works fine, but only works with whole numbers. How, if possible, could I output values with decimal points. ie: 6.2+2.4 outputting 8.6.

Set /a S=6×2

%S%

Thanks

Mark

for /F "delims=" %%G IN ('powershell -command "2.4 + 6.2"') do set "result=%%G"

The command processor has a limitation when it comes to floating point arithmetic. Have a look at this workaround:

Note: You can get your decimal back with string manipulation on the result.

Thanks for the quick responses.

@atfon. l was reading the workaround you linked whilst you were replying. What exactly do you mean by string manipulation to recover the decimal point?

Thanks

Hello Mark. You can extract the first digit and the last digit:

For the first digit, set "first=%str:~-1%" and for the last set "last=%str:~0,1%". Then you can set the entire term as set "whole=%first%.%last.%"

There are likely easier ways to do this that the Experts on this site could point out to you. For example, Squashman's powershell example or VBScript.

Thanks for that.

I'm incorperating into ffmpeg scripts so will take a closer look at the best approach for my needs.
