Finding Number Inside a Cell

Got both codes to work!!!

Getting late so am going to call it a night, but will post them both
tomorrow with questions I have on your code Rick.

As for JLatham's method, I actually understand it all plus some extra
things I added into it as well (like an if statement to detect a minus
and delete it, but skip over that step if it's 0).

This is all to be used for a point measuring system which originally
was created and modified by hand, but now can be modified by macro and
hopefully speed things up.

Thanks for the help, check back in tomorrow to take a peek at the
codes which I'll post so that those looking for clues, tips, and to
pilfer by archives searches have some useful fodder.

Since, NP

After giving it a good 10 minutes go, I had to do a little bit of
variations, but otherwise much easier than my current system. For now
though, much harder for me to understand what's going on.

If you have any questions about what is going on in the code, feel free to
ask.

NEEDS A CORRECTION.
After reading one of your posts, I realize that the constant
numericCharacters needs to have the decimal point added to it. If you try
that code out, change that line to read:
Const numericCharacters = "0123456789+-."
The change in the sequence of characters in it will probably improve
performance just a tiny bit since the probability of encountering a digit is
higher than one of the +, - or . symbols.

The following code will work for the examples you've provided, given that all
entries are exactly like the ones you've provided, it should work for a list
of similar type entries. There is a good chance of it failing or locking up
in places if the entries in your list don't follow the same format of your
examples.

I leave it for the student to investigate Help on any unfamilair VB commands
used.

I don't know enough about VBA yet to do this without help.

I have a column of variable tolerances which have one of the following
forms:

5 ST 5.3 (aka number, space, "ST", space, desired number)
5 +-6 (aka number, space, +- symbol, another numberm)
5 +4/-2 (aka number, space, positive number, /, negative number)

I need to be able to extract the tolerance numbers in order to use
them for conditional formatting.

I would want the following from the above:
5.3 (there is a set tolerance off this number, so all I need is this
number, I don't need 5 at all).
5 and 6 to turn into -1 to 11 (the max/min of the tolerance).
5, 4, and -2 to turn into 3 to 9 (the max/min of the tolerance).

This surely involves finding spaces, /, etc., and determining what is
what, but I'm having a lot of trouble getting things to work in VBA.

Suggestions and existing code to improve much appreciated.

Thanks, NP

Hehe... don't worry about it JLatham. I already added that in !!! I
realized it was deleting it so took a guess and got it.

That being said, for the people (most likely now archive browsing folk
of this group), here are the two solutions for the problem of
extracting numbers for stuff within a cell.

Again, I'm posting these so hopefully people like me who try to use
the archives first to figure stuff out can copy/paste this into Excel
and understand it / alter it to satisfy their needs.

As the saying goes, good poets borrow, great poets steal.

Note here that with Rick's solution, I hadn't put in conditional
formatting yet.
This is really quite easy, the tough part was getting the max/min (or
high/low) to get a correct readout.

I still need to sit down and look at the code to understand it. Maybe
I'll try to think of some similar type program to write and try out to
test myself afterwards. Regardless, in the future a question or two
may come, but for now, here's Rick's solution laid out.
