[+]new feature
[-]bug fixed
[*]feature improvement
[!]announcement

Version 2.1.198
==================
[+]support DBCS characters (such as Chinese characters, Japanese characters etc.) as variable name and custom function name
[+]use the default value in the variable assignment operation if the expression has any errors, eg: A=\5, it will give an error and the value of variable A will be NULL in the former version. From this version of #Calculation Component, it will use the default value 0 as its value.
[*]optimize the speed of variable management
[*]improve the 'Scientific Notation'
[*]improve the way to handle the variables in custom functions
[*]improve the error capture, more accurate than before
[-]undefined functions bug, eg: F(1) should give an error information, because F is not a defined function. But in the former version, F will be seemed as a variable.
[-]remove matrix dimension warning
[*]other little tweaks

Version 2.0.2368
==================
[-]a bug in 'String Conversion' has been fixed, this bug can cause error 5 messge in every calculation process, and the bug according to the Windows OS you use, not everyone can meet it.

Version 2.0.2126
==================
[+]support string data type operation
[+]support date&time data type operation
[+]new String functions
[+]new Date&Time funcitons
[+]new Financial functions
[+]new MessageBox functions
[+]you can use the variables named the same as system functions now, eg: len=5,left=6,max=7 etc.
[+]& operator for string concatenation
[+]Like operator for strings comparision
[*]improve the existent functions
[*]optimize calculation speed, 3 times faster than before
[*]new method to handle variables, much faster than before
[*]improve 'Simulate the exact value' operation, eg: arcsin(1)*2 will give the result Pi
[*]new handle-mode for custom functions
[*]new way to handle variables in custom functions
[*]the operators /,\ in matrix operation be seemed as ./,.\ temporarily
[-]a bug in 'Scientific notation'
[-]a bug when using a null string as the function parameters
[-]no expression bug, eg:(),[] etc.
[-]the bug in assignment operation, eg: b=a=1 should be b=1,a=1 and the expression value is 1. But all of them are 0 before.
[-]no operands bug in duality operators, eg: 5+,5-,5* etc.
[-]a bug in variables assignment operation inside custom functions
[*]the sample codes according to the new version of the component
[*]the help document of #Calculation Component

Version 1.5.258
==================
[+]begin to support Matrix and Array operation now; it is easy to realize the matrix operation just like MATLAB and more powerful "EXCEL similar" custom functions
[+]use matrix as the parameters of the system functions and the custom functions
[+]the property "SimulateExactValueEnabled" to control whether or not to use the "Simulate the exact value" operation
[+]the property "ZeroPowerEnabled" to control whether or not to use "0^0=1" operation
[+]dot operators (.*, ./, .^, .\) for matrix operation
[+]left division operator "\"
[+]12 new built-in functions
[+]the feature that a matrix or an array will be seemed as a whole item such as a number or a variable etc., so you can get a matrix or array result now
[-]the parameters error when use the multi-parameter functions
[-]the problem that the error information is imprecise sometimes
[-]some problems when use the operators "mod" and "div" in the expression
[-]"No response" problem while doing a huge calculation
[*]70% code of #Calculation Component has been rewritten for supporting matrix and array features in the kernel of the component
[*]many new methods have been used to replace the old realizations in order to improve the speed of calculation process
[*]the sample codes according to the new version of the component
[*]the help document of #Calculation Component

Version 1.1.166
==================
[+]Binary System, Octal System and Hex System support
[+]the mixed operation for Binary, Octal, Decimal and HEXadecimal numbers
[+]many new property and new methods of the control
[+]edit and del the custom functions as you like
[+]Description for custom function
[+]system function "round" for End User as Round function
[+]make "Round Operation" according to the appointed bits
[+]Base-N(2,8,10,16) results can be showed now
[+]a new RegTool has been included into the Formal Version of #Calculation Control Package in order to make the registration process of the control on developer's computer conveniently
[-]the "Infinite Loop" bug when use nesting custom functions
[-]no operators bug between two system functions
[-]the bug that the system functions arcsec(1), arcsec(-1), arccsc(1) and arccsc(-1) can not be calculated
[-]the problem when register the control on the End User's computer with your application
[-]some other little bugs in the former version of #Calculation Control
[*]custom function managing process
[*]the algorithm of some system functions
[*]the data structure of #Calculation Control for developer
[*]the sample programs according to the new version of the control
[*]the help document of #Calculation Control
