Hi,
I have a similar question and need help. ( WORKING ON .MCD12 )
Finding the 6-decimal numbers and marking. (like as above)
Thanks in advance.
Regards, -LL-

This marks a specific number of decimal places. It's a bit of a mixed up approach, but I think it should be reliable. It would be less mixed up if I also used string functions to find the number of digits before the decimal point, but the ceil(log) approach was the first thing I thought of and I'm too lazy to change it

Do you mean something like the attached, using search?

Very nice.
Can we stop adding additional functions / methods - I'm struggling to document all the examples

Something like that, yes.

Too right! One must be careful not to waste flops. Wasted flops means wasted energy, which leads to global warming and the end of the world as we know it!
The majority of what I know about Mathcad I have learned from others that posted to the Collaboratory. Stuart is one of many. I am still leanring. That's a good thing, because if one is no longer learning then one are either senile or dead.

Is this what happened to Jean? Was he neglecting to balance his flips with some flops and getting overheated? It certainly lead to the end of the Mathcad World as we knew it. I suppose the question is are we mammals or dinOsaurs looking at that old meteor headed towards Chicxulub?

Err, Jean? Wakey, Wakey.. RUUUUNNNN!
Jean, burying your head in the sand won't help You said the calculations showed it would miss us! I told you we should have used units!

ROFLMAO!!!! 
I wonder if Mr Lamb is still around? - I think he'd appreciate the astronomical and unit references. 
Richard, it seems that I understand your idea on above, so I would update my question as similar one.

Couple of ways to get started.
1. If you use a version of a function that iterates through the vector and uses an expression involving the index, then simply replace the 'value' with the index.
2. Use a simple 'filter' functions that iterates through the 'normal' result and replaces each nested array (marked element) with its index.

Slight alternative attached.
I have combined into one program so the function is only dependant on one pre-defined function.

Oh. I see. If somebody else suggests a new method then you can't keep up, but if Micheal suggests one ... (exit. stage right. flounce.)
I like the use of match, but it is possible to make slightly more efficient use of the results. OOIC, why did you add one to the index?

Ok. I give up you win..... I like this game though.
WIWAC, I only got angry with people once; I was lead on a 4 hr exercise (tracking some evaders). 10 minutes before endex, I reckoned the 'enemy' had passed through the area I was staking out and got the team to load up on the 4-tonner to head for the next point I thought the enemy would head for. The team got on the lorry, then just sat down looking inwards. Sudden transformation on my part from Mister Quiet to Raging Fury - get off your backsides and get looking 
. Got the enemy 2 minutes later!
So the moral of the story is "Don't give up. It ain't over 'till the fat lady sings.". It is a good game, and I draw inspiration from both your's and Richard's solutions.
So many ways to skin them, so few cats
or is that, so many ways to kill them, so few lawyers?
(WIWAC - When I Was At Cranwell)
I added 1 to the results just to match the original request - Just having one of those moments, sorry!!!!!!
Mike
Ah, OK. I assumed it was because they were using ORIGIN=1. The match solution should work, provided the function is defined where ORIGIN is 1.

ORIGIN = 1 ----- Of course.
Another moment where my brain cell got a little overloaded.

As Richard says, the numeric processor won't handle that many digits due to the (IEEE standard) floating-point format that Mathcad uses to store numbers. OTOH, you could use the symbolic processor ...
