v1.8 [Jan 15, 2012]
* finished Dutch translation of new texts for version 1.8 and translated units.xml by Karel
* correction of the Czech translation, translation of the basic geometric formula library and units.xml by Josef Pavlík
* translation of new features in French manual by Pierre Yves Baumann
Improvements:
* Unit converter:
o Automatic conversion of the input value during editing
o Automatic selection of the first category after units are loaded
o Improved form layout (optimized for resizing)
o Removed Calculate and Close button from the form
* Translations:
o finished French translation of new texts, unit file and license by Pierre-Yves Baumann
o finished Russian translation of new texts, constants and basic geometric formulas by Viktor Fyodorov
o Chineese translation of program texts, basic geometric formulas and unit file by Diqiuyi
o finished German translation of new texts, unit file and manual by Uwe Reisinger
* Modified layout of several forms to match longer texts in some languages
Fixes:
* Invalid memory access when editing a constant
* Function arctanh didn't pass expression control
* Displaying expression change warning icon when the Back button was used
Improvements:
* Added new tools: unit converter and quadratic equation
* New window with basic prefix values, which can be easily inserted into the expression
* Program can remember the state it was in during the last execution(chosen number set, angle mode, precision, and so on)
* New setting window with more available settings:
o what to insert as new expression after evaluating the current expression and inserting an operator
o what to use as a decimal separator (dot, coma, or the operating systems default separator)
o choosing between mathematical and electrotechnical format of complex numbers (5-2i vs. 5-j2)
o programs default state (the state right after start - chosen number set, angle mode, precision, and so on)
o result notation: ordinary (0,02) or exponential (2E-2)
o the evaluation result can be automatically copied to clipboard
* Improved Graph of function
o Added status bar with information about the x and y values on the current cursor position, and also about the functional value in that position
o Default view is not x=0 and y=0 anymore, but it depends on the function value in x=0.
o The whole graph can be easily copied to clipboard or saved to file using the export buttons
* Added new functions that can be used in the expression - gamma, sec, csc
* Factorial can be calculated also from real numbers
* Automatic info about new versions is less annoying. Only a small icon is shown in the bottom right corner of the main form instead of a dialog
* All tools now accept input values also in exponential notation
* Added a warning icon that is shown when you modify the expression, and the result is no longer valid
* When changing the numeral system, also the precision is changed to fit the new numeral system
* The program is by default translated into English (in case the translation file is not found)
* Optimization of GUI memory usage
* Optimization of the evaluation algorithms (expression evaluation is now approximately 14% faster)
* A warning message will be shown in case that you are creating a new library file in the expression browser, and you try to save it in a different folder than the library folder
* Pressing the Esc key in the main window will delete the current expression and result (same as clicking the [C] button)
Fixes:
* The main window couldn't be moved from the main monitor on computers with more then one monitor.
* Invalid memory access, in case that no constant file was found, and you tried to edit the default constants (pi an e)
* Bad file extension in the Expression browsers save to file dialog
* Bad encoding of the "result=" label in the combinatorics tool (it was causing trouble with the Russian translation)
