March 2014, v2.4
First of all, an important note.
If you had any previous
version of CCCalc installed then when you run this one for the
first time, its window may appear in a wrong place
of the screen and will be inconveniently
small. Sorry for the inconvenience. Please adjust its size and location once and CCCalc
will remember your new setting.
1. Localized decimal separator
separator is localized, e.g. CCCcals will show "123.12" for
USA locale, but "123,12" for German, Russian etc.
2. Comments move-out
If you don't use comments and want them not to
waste the screen space, then now you can simply
scroll comments out the window border. After that
CCCalc will show comments only if you scroll them
back in, or press TAB to set the caret to the
3. Input Improvement.
Now if you type
"2+++" key sequence it will result to expression "2+2+2+2=8",
not to "2+0+0+0=2" as it was before. The new behavior
conforms to pocket calculators better.
4. Remastered German localization
Many thank to it's author, Lesmo16, for this and
many other contributions
to this project.
5. Bug fixes
- CCCalc text now
flickers much less during scrolling.
- Bug fix in pasting data from another applications,
which caused to produce wrong paste results for data with
whitespaces, especially from Microsoft Excel or some web
October 2013, v2.3: Text auto cleanup
Now you can set up CCCalc to clean up the calculation
history each time you run it.
- Improved appearance on high-resolution
screens on Windows Vista, Windows 7 and Windows 8
- New layout for on-screen virtual keypad which
conforms better to traditional desktop and pocket
- Setting dialogs are redesigned to look better
- Fixed crash of CCCalc on
computer wake up after being asleep
May 2012, v2.2: Text comments
Now CCCalc allows you to put text comments into
1. HTML clipboard format support keeps
calculation appearance when pasting them into office
2. Bug fix
In version 2.1 it was impossible to start typing
a number from the decimal dot.
December 2010, version 2.1: Printing
Now you may print the calculation tape
1. Minimize window instead of program termination
The new option sets the CCCalc to not terminate
when its window is closed, like, for instance, the
Skype™ application does.
2. Improvement in expression input
When CCCalc inserts a new number while you
entering an expression, it now uses a copy of the
previous number instead of zero, which is marked as
a current selection. This makes no changes to a key
sequence needed to enter an expression in general,
but gives some small conveniences. For example, to
calculate any number squared you need to enter it
once and press "*".
3. Special button for change sign operation
The new button of the virtual keypad which
changes sign of the current number makes this
operation more obvious and convenient.
Thanks to all people who shared
these cool ideas with us!
April 2010: version 2.0
1. You may save as many calculation histories as
It is done via traditional menu commands "Save
As", "Open" and "Close" like in many other
applications. The difference is that CCCalc still
saves current history automatically and invisibly,
so such actions work like switching CCCalc to
another file which will be in use, even if you
reboot the computer, until next such explicit
To open a file you may also double-click it in
the Windows Explorer window.
2. Update notifications
CCCalc will notify you itself when a new version
or update is published, no need to check the site
3. German localizations
Thanks to Lesmo16, who volunteered
in the translation and respective testing, the
program will "speak German" if it is the language of
October 2009: version 1.9
1. Virtual keypad added
It contains buttons for almost all action
available in CCCalc. The keypad is provided for people
who prefer using mouse instead of keyboard. It also
makes it easier to know what is possible here
and what is not.
2. Personal calculation history
Calculation history now is saved in personal user
profile instead of Program Files. It solves the
problem with lack of write permissions on Windows
Vista and also provides personal calculation history
for each user on the computer.
3. A number of usage
For instance, now when you insert square root
sign, CCCalc keeps the caret not moving and so you need not to move it
explicitly to add operation after this number.
4. Internals refactored
It greatly simplifies future UI improvements, and
the first one of this kind is the virtual keypad.
May 2008: Version 1.8

or right-click popup menu

All these was done by request of our customers.
Thank you all!
