I tried to compile the newest version. However, CMakeLists.txt says:
cp ARGS -f i18n/*.qm ${speedcrunch_TRANSLATION_DIR}
But there are no qm files i that directory in the newest version (0.10.0 still has them!).

liquidat: you need to run "lrelease speedcrunch.pro" to build the QM files. It will be fixed in the next version, see http://code.google.com/p/speedcrunch/issues/detail?id=194

Hi!

I don't have Qt4 and I don't have permission to install it on my computer. Could you please provide any old tar ball? (I looked through the revision and it seems that Qt3->Qt4 change was done around version 7... so please provide me a link to version 6 tarball!

Thanks

In Norwegian we use , and not . as decimalpoint. I haven't found any settings in 0.7-beta1 (win32) where I can select this.

The best thing would be to use the systems locale settings.

Will be considered in the future version.

Meanwhile, if you press comma (,), it will be regarded as point (.).

I have just downloaded SpeedCrunch Version 0.7 Beta-1 and performed the following tests, using 50-digit precision:

SPCR sin(10^22 )= -8.52200 | 918050626935619363157432839453863959329520531e-1
PariGP sin(10^22) = -8.52200 | 84976718880177270589375302936826176215041004e-1
SPCR cos(10^22) = +5.23214 | 674176545467019501300134952278548556645769073e-1
PariGP cos(10^22) = +5.23214 | 78539513894549759447338470949214091997243939e-1

As you can see, SpeedCrunch performs very badly. It may have high precision, but it has only 6-digit accuracy in these tests. By the way, the standard Windows 2000 desk-top calculator has 32-digit accuracy.

If you want to see how difficult it is to write real numerical software, have a look at this paper : http://www.derekroconnor.net/home/PAPERS/Ng--ArgReduction.pdf

I found this app very handy and useful. Thank you for the job!
But I am missing one feature. I would like to do calculations with time values for example 160 min + 10 hours, show 3250 seconds in hours, minutes and seconds, add 120 days to 1st July 2004 and so on. I am missing such simple time calcularor on both Windows and Linux, so I hope speedcrunch will implement it :-)

When I work with this program, i don't use mouse at all and it's not comfortable to find when I wish to close calculator or so (yes, Alt+F4, but...). Something such as clearing with Escape, commands 'cls, insvar, insfn' (or names that you want) may be useful.

Great work. What I'd like to see in next release (and probably not so hard to implement) is a function for sums.

Like sum(var,lower,upper,expression) evaluating expression by replacing var from lower to upper and summing up the results...

but the calculator is still usable :D

Since SpeedCrunch is the new default calculator for Kubuntu Breezy, calculate has become a lot easier! Thx. I'm looking forward a complete integration in KDE. Here are some suggestions: SpeedCrunch as a KPart: typping sc:/something to calculate in Konqueror bar could display the result in the tab;Maybe a more KDE-like name? what about SpeedKrunch?Symbolic calculation. I really miss an calculator equivalent to the TI92 under KDE (powerful but easy to use). I have a computer 10,000 times more powerful than a TI92 but still have to use some esotheric language to derivate, integrate, compute series;Possibility to copy the calculus in Klipper using different format (KFormula, OpenOffice Math, LaTeX, image generated by LaTeX...).

Is there a possibility to calculate with numbers in hexadecimal and binary notation? A conversion between those would be nice, too.

My suggestion:
0xA1 should be interpreted as hex => 17
0b1001 should be interpreted as binary => 9
everything neither starting with 0x nor with 0b should be intepreted as decimal.

For the conversion, there should be functions hex, dez and bin.

first, thanks for this new relase!

i found some bugs:

1. if i enter "sin( 1)+" crunch does not accept the last +, it writes a ) instead.

2. the function-auto-completion pops up on my left monitor while crunch is on the right (i use xinerama)

3. the enter-key on the numblock doesn't evaluate

4. feature-idea: it would be sometimes nice to have the list of all variables directly in the main-window (like abakus does)

Thank you for your interest on SpeedCrunch!

1. It works for me. Could you describe again step-by-step on how to reproduce this?

2. I don't use Xinerama so I can't check. Could you contact me via e-mail so I can send you a patch which you can try and check?

3. Oops! I'm on laptop so I never check this :-)

4. Future version will have non-modal variable dialog.
