Via the magic of number_format() we have this fixed!

2*2*2*2*5*5*5*5
73*137
2*3*1,667
7*1,429
2*2*41*61
3*5*23*29
2*5,003
10,007
2*2*2*3*3*139
10,009
2*5*7*11*13
3*47*71
2*2*2,503
17*19*31
2*3*1,669
5*2,003
2*2*2*2*2*313
3*3*3*7*53
2*5,009
43*233
2*2*3*5*167
11*911
2*5,011
3*13*257
2*2*2*7*179
5*5*401
2*3*3*557
37*271
2*2*23*109
3*3,343
2*5*17*59

Also, the forced setting of "1" for private messages has now been changed to a random number because it looks neater and because it is more confusing, which is always fun!

Fixed!



Edit1: Adding spaces takes up too much room. The display will continue to another line but it looks weird.
Edit2: Special thanks to this web page for the ability to prototype rapidly and this web site to make our code less ugly.

Is it feasible to utilise ISO 8601 universal style dates, e.g. 2016-03-11?
The petition to do that at mersenne.org was successful, with Madpoo's efforts appreciated.
I suppose that would depend on such being provisioned by an appropriate version of vBulletin.

It would be an option.

Date formats are a very volatile subject here, for some reason. You would need to get a lot of members to agree with the change. Any time we mess with the format even the littlest bit everyone goes bananas. (Maybe make a poll?)

Actually I think this is one of the easier ones. yyyy-mm-dd date format is the only logical math-y forum-approved date-format. A poll should show the clear consensus on this one

That will require a new approach to our code.

Instead of immediately concatenating a factor, increment a counter. Then concatenate a power if the count is > 1. Sure, it will be some more lines of code, but not a whole lot complex.

Also, if you haven't implemented the i*i<=x condition in while loop, I strongly advice to do so. For larger numbers this could lead to substantial savings.

We would also like to substitute "×" for "*". And maybe add commas to parts that are more than three digits.

So:

2 × 3³ × 1,234

For now we are happy with the results.

If $t is the expanded factor string...

implode('×',array_map(function($v,$k){return $v>1?"$k[ sup]$v[/sup]":$k;},$a=array_count_values(explode('×',$t)),array_keys($a)));

... minus the space before sup.

This one is real ugly, but it works:

Sure, it will have to guess which part to factorize in primes, and which part to let unfactored to look nice (i.e. do not factor 1234 into 2*617, because it looks more nicer when written 1234, you know, consecutive numbers... blah blah...)
