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

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
MOD: 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 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!

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

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 :-)

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.

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)

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.
