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.

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.

Thanks for making this BGM. I think I may have come across this in one of its earlier version. After re-testing it has now replaced Numculator as my go-to calculator due to the swiftness of its launch.

Specular on 2019-05-21 10:17

@billion any idea where I could find the changelog for 1.8+? Could only source up to 1.7 on the documentation site.

billon on 2019-05-21 11:44

@Specular:

v1.8 wasn't announced even on DonationCoder
Maybe v1.9 changelog is summary for 1.8 too?
Or maybe BGM himself can clear this?

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. :)
