@CarlLange I love how it says "Please consider adding a comment if you think this post can be improved." when you downvote the post. Why, yes, if that is what you need from me :P

Howdy-hoo

I'm interested in the inverse mapping of "Part"

So suppose I have a list {a,b,c,d,e}

I define it to have the name "unimaginitive", so unimaginitive = {a,b,c,d,e}

unimaginitive[[3]] then gives c for example, so far so good

I'm now interested in a function that has output "3" when I do <thisfunction>[unimaginitive,c]

@1010011010 Is Position close enough? It's more properly the inverse of Extract.

@MichaelE2 Exactly what I needed!

Knew I could count on your guys, cheer

Interesting?: Solve[0``10*x^2 + 0``10 == 0, x, Method -> Reduce] indicates no x is a solution (with or without the Method option) and Reduce[0``10*x^2 + 0``10 == 0, x] indicates all x are solutions. In the case of Reduce, the output switches from True to False when the degree on x changes from 10 to 11.

I've got multiple MMA versions; for some reason 10.3 gets stuck updating unlike the rest

seems like mathematica.stackexchange.com/questions/92931/…

or maybe its my weird internet connection on the train! :)
