Need help with this little program

[AceInfinity]

Actually, I used the one line code that you have quoted but was the same error.
I now realize that the problem is not in code, it is in the combination of number I input to the program

Thanks for your brilliant time that you gave me

Hmm, if I was a quadratic equation formula expert i'd be able to help you further haha, sorry about that friend

I recognize the equation, but it's been some time since I last used it.
