Description: SpeedCrunch is a fast, high precision and powerful desktop calculator. Available for Linux, Microsoft Windows, and Mac OS X.
Few of its distinctive features are:
* scrollable display * up to 50 decimal precisions * unlimited variable storage * intelligent automatic completion * full keyboard-friendly * more than 50 built-in math functions * optional keypad
SpeedCrunch 0.10.1 --------------------- Bug fixes: Fixed keypad button "=" [#176] Fixed incomplete math book link upon clicking [#177] Fixed potential crashes [#180] Fixed back and forward buttons have the opposite meaning in RTL [#185] Fixed missing window update on radix character change Updated binreloc to build in LSB environments
Improvements: Better handling of math book translations with language codes that contain the country component and now correct behaviour defaulting to English when the system language (selected option) is not supported
Internationalization: New Basque, Catalan and Simplified Chinese translation Updated translations Removed Slovenian language menu entry, since there is no such translation available
Packaging: New Mac OS X Universal Binary finally available (first since version 0.7)
SpeedCrunch 0.10 --------------------- New features: Preliminary support of logic functions Extended output of real-valued numbers to non-decimal modes Allow real-valued arguments for nPr and nCr Restore last session Save and load session Ability to change language on-the-fly Context menu for tray icon Support for RTL (right to left) written languages Batch calculation Minimal view version Default desktop file for menu integration New Turkish (incomplete) translation Math Book browsable pages in a dock window Compile-time option to build a "portable" target Full screen mode Automatic syntax highlighting color generation Status bar Auto-calc of the selected text
New functions: ERF: the normalized error function (related to normal distribution) ERFC: the complementary error function GAMMA: the extension of the factorials (x-1)! LNGAMMA: ln(Gamma(x)) for x > 0 IDIV: integer division MO modulo
Improvements: Improved binomCdf evaluation allows n to be as big as 20000 now Improved keypad Testevaluator independent of locale (does not use ',' any more) Exp/Log inconsistency New keyboard shortcuts (including PagDown/PgUp to scroll result display) Redesigned menus Optional widgets created and destroyed on the fly, optimal for mobile devices Click to copy and double click to insert an expression from the display into the expression editor Errors displayed in modal dialog instead of result display Selecting and inserting an expression does not trigger evaluation
Bug fixes: Fixed loss of precision on variable saving Fixed clobbering of ans on radix change Fixed a bug in the math engine (float_frac) that could cause memory corruption Bugfix in the pochhammer symbol evaluating routine, affecting nPr when n and r are negative integers, and n == r-1 Bugfix: No freeze any more when evaluating (-n+0.5)! for very large integers n Bugfix: cbrt fixed for values 1+x with x
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.
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...
first, thanks for the great application...
second, the bug that the autocomplete-popup appears on the wrong monitor when using xinerama is still not fixed...
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.

Can You provide static binary file?

Will be considered in the future version. Meanwhile, if you press comma (,), it will be regarded as point (.).
So this is now supported in version 0.8.

did you try date? date -d "2004/7/4 00:00 +120 days" date -d "2001/1/1 00:00 +160 min + 3 hours"
What about binary and hex view? I would like to see something like this: http://alextp.hotbox.ru/ecw/index.htm

this is the correct one for 7-BETA1: http://speedcrunch.digitalfanatics.org/speedcrunch-0.7-beta1.tar.gz Gonna chew some digits, great app, no, better: a real 'utility' !!

Are there any Gentoo ebuilds?
