Not portable, check forum for details.

Smath Studio currently at Version 0.99.6671 is better and without any limitations. It is reacheable under https://en.smath.info/forum, but one should read SmathPrimer.pdf before using the program.

By the author of Ubiquitous Player:

I've decided to stop updating this program. In 3 years I received exactly zero feedback on it, so I guess no one really uses it.

Thanks.

shnbwmn on 2016-05-17 21:37

So ... is this program being actively developed again now?

MIKLO on 2016-08-23 14:32

WOW this is still being updated I'm surprised but anytime someone is willing to improve their software 4me its a good thing. I used this some time back it does a lot of things but to me is just way to busy although it did work well when I used. :)

@Checker, haha. It might be a good idea to change the link seeing as the main site has been down for a while.

According to the About box of my Numculator install the latest version is actually 3.0.156, but maybe I'm missing what you mean.

Checker on 2015-08-05 20:58

@ Specular: Oops, you are right - I was following a wrong link (not joby_toss's).
BTW: It's v3.0.0.156 (not v3.0.156) ;)
So it was indeed a nice way to introduce a version update - thanks ... and updated ;)
Links set to Softpedia.

Checker on 2015-08-05 21:14

'Program about' says: v3.0.156
'Numculator.exe about' says: v3.0.0.156 ... strange!
I changed the database entry back to v3.0.156 (according program about and Softpedia's entry).

Heh, you're right, the integrated "cbrt" function fails for numbers beyond a certain limit. My bad.

nah on 2010-11-24 20:48

The aforementioned bug has been fixed in the 0.11 alpha. Haven't found any new ones (hopefully won't either). Very nice approach.

smaragdus on 2015-01-30 09:23

The keypad has been removed in version 0.11 which I don't like- in the previous version of SpeedCrunch- 0.10.1, it could be easily shown/hidden.
