ttcalc/CHANGELOG

Version 0.8.3 prerelease
    * fixed:   calculating the size of the main window
               now it looks good on MS Vista and when a user changes size of some
               widgets such as a border, font size, etc.
    * changed: variables and functions are case-sensitive now, e.g.
               'x' is not the same as 'X'
    * changed: precision:
               small  - the same as previous
               medium - 288 bits for the mantissa, 64 bits for the exponent
               big    - 864 bits for the mantissa, 128 bits for the exponent 	
               previous were:
               medium - 192 bits for the mantissa, 64 bits for the exponent
               big    - 288 bits for the mantissa, 96 bits for the exponent
    * added:   when a user presses CTRL+C then the result will be
               copied into the clipboard (if the current control which 
               has a focus is not an edit control, or if it is an edit
               but has no selection)
    * added:   when a user presses CTRL+V then the text from the clipboard
               will be copied into the edit control
               (the focus can be anywhere but it cannot be on another edit control)
    * added:   'decimal point' option on the display tab
    * added:   variables and functions can have underline characters
               in their names
    * added:   from TTMath 0.8.3: a short form of multiplication
               (without the '*' character) e.g. '5y'
               (it's used only if the second parameter is a variable
               or function)
    * added:   'remove trailing zeroes' option on 'display' tab
    * added:   new language: spanish
               translation made by Alejandro S. Valdezate
               alesanval at gmail dot com
    * added:   spanish language to the setup (installer)
    * added:   the setup will remove mingwm10.dll if it exists in the program
               directory
    * added:   on display tab: we can select 'deg' 'rad' or 'grad' for calculating
               in such functions: sin,cos,tan,cot,asin,acos,atan,acot
    * removed: 'cut off last non valid digits' on 'rounding' option
               on 'display' tab


Version 0.8.2 portable (2007.07.01):
    * added:   the portable version of the program TTCalc
               it uses *.ini config file from the same folder where
               is the executable file, and it's much smaller in size
               (in the portable version there's only one kind
               of precision and the program is packed with UPX - 
               the Ultimate Packer for eXecutables)
               there are no other differences between version 0.8.1 and this one


Version 0.8.1 (2007.04.17):
    * changed: on win9x the configuration file is in a folder like:
               "c:\windows\data application\ttcalc\" now
    * changed: the program uses the TTMath 0.8.1 now
    * added:   from TTMath 0.8.1:
               root(x, index), bitand(x,y), bitor(x,y), bitxor(x,y)
               /band(x,y), bor(x,y), bxor(x,y)/
               asinh(x), acosh(x), atanh(x), acoth(x) /atgh(x), actgh(x)/
    * changed: from TTMath 0.8.1: calculations are much faster now
               especially the factorial() function
    * changed: from TTMath 0.8.1: the way of parsing operators


Version 0.8.0 (2007.04.02):
    * added:   the del key deletes a variable or a function now
               (if the focus is on the list)
    * added:   a user can change the names of variables or functions now
    * changed: the program uses TTMath 0.8.0 now
    * added:   functions: from TTMath 0.8.0:        
               DegToDeg(deg, min, sec), DegToRad(deg), DegToRad(deg, min, sec),
               RadToDeg(rad), Ceil(x), Floor(x), Sqrt(x), Sinh(x), Cosh(x),
               Tanh(x) /Tgh(x)/, Coth(x) /Ctgh(x)/
    * added:   help
    * changed: from TTMath 0.8.0:
               renamed: CTan()  into Cot()  or Ctg()
               renamed: ACTan() into ACot() or ACtg()
               Factorial() has a history log now (it can remember last
               10 calculated values)
    * fixed:   the vertical size of the main window when a user uses a different
               size of the window caption (especially under the Windows XP Luna)
    * fixed:   on Windows 9x: the program hung when a user clicks on a control 
               on the first tab
    * fixed:   when a user started navigating from the keyboard the program showed
               a wrong variable or a funtion in the edit dialog


Version 0.7.3 (2007.03.08):
    * added:   the program shows some kind of errors itself
    * added:   checking whether an user has inserted a correct value of a variable
               or a function
    * fixed:   navigation from the keyboard
    * changed: the esc key selects the entire input text now (in the input edit)
    * added:   a test when the program is being starded which checks if the
               coordinates of the main window actually pointing at the valid area (for
               example when someone took his configuration file into a new computer and
               the new computer has a smaller screen)


Version 0.7.2 (2007.02.28):
    * added:   buttons Sgn and Mod
    * changed: the button 'err' is active when there's actually an error now
    * added:   buttons: ASin, ACos, ATan, ACTan
    * fixed:   the program didn't save the current language into the configuration file
    * fixed:   the second thread didn't read the main window correctly and it caused
               small problems when an user was typing into the first edit control


Version 0.7.1 (2007.02.08):
    * added:   button 'err' (error) on the first tab
    * changed: the input edit can have 2048 characters now
    * added:   remembering the vertical size into the config file
    * fixed:   a problem with the 'tab' key
    * added:   a message 'Calculating...' when an user clicks on the 'err' button
               during calculating something
