How can I determine the maximum absolute value of a vector, but have the result appear with its corresponding sign?. 

Thanks to the community for your attention.

Hi,

I took a different tack without the programming.

Cheers

      Here are my 2 cents worth...

       

      Like Terry I wondered what you would like to chose in case positive and negative values with the same absolute magnitude exist.

       

      Here are some suggestions:

      P.S.: The method also works well in the free Prime Express. But because Express does not offer programming, we would have to change the "magnitudes" function in Express and do without the local variable "absv":
