+    Changes from TTMath 0.8.5 relating to TTCalc:

+               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:

+               big    - 288 bits for the mantissa, 96 bits for the exponent
+    * changed: new version of TTMath bignum library: 0.8.3
+    * 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:   'remove trailing zeroes' option on 'display' tab

+               translation made by Alejandro S. Valdezate
+               alesanval at gmail dot com

+               in such functions: sin,cos,tan,cot,asin,acos,atan,acot
+    * added:   when the program exits new variables and functions are read from
+               the configuration file and then the file is saved
+               (if you have inserted some variables or functions in a different
+               instance of TTCalc those variables or functions were previously
+               skipped)
+    * removed: 'cut off last non valid digits' on 'rounding' option
+               on 'display' tab
+
+    Changes from TTMath 0.8.3 relating to TTCalc:
+    * fixed:   Big::Add incorrectly rounded 'this' when both exponents were equal
+               it caused that sometimes when adding a zero the result has changed
+               this had impact among other things on FromString() method
+               "0,8" had different binary representation from "0,80"
+    * fixed:   Big::Pow(const Big<exp, man> & pow)
+               it's using PowInt() only when pow.exponent is in range (-man*TTMATH_BITS_PER_UINT; 0]
+               previously the powering 'hung' on an input like this: "(1+ 1e-10000) ^ 10e100000000"
+               (there was 10e100000000 iterations in PowInt())
+    * fixed:   in function DegToRad(const ValueType & x, ErrorCode * err = 0) it is better
+               to make division first and then mutliplication -- the result is more
+               accurate especially when x is: 90,180,270 or 360
+    * fixed:   the parser didn't correctly treat operators for changing the base
+               (radix) -- operators '#' and '&', e.g.:
+               '#sin(1)' was equal '0' -- there was a zero from '#' and then
+               it was multiplied by 'sin(1)'
+               the parser didn't check whether Big::FromString() has actually
+               read a proper value -- the method Big::FromString() didn't have
+               something to report such a situation
+    * fixed:   Big::FromString() when the base is 10, the method reads the scientific
+               part only if such a part it correctly supplied, e.g:
+               '1234e10', '1234e+10', '1234e-5'
+               previous '1234e' was treated as: '1234e0' (now parsing stops on 'e' and
+               the 'e' can be parsed by other parsers, e.g. the mathematical
+               parser -- now in the parser would be: '1234e' = '1234 * e' = '3354,3597...' )
+    * changed: in the parser: the form with operators '#' and '&' is as follows:
+               [-|+][#|&]numeric_value
+               previous was: [-|+][#|&][-|+]numeric_value
+    * changed: the parser is allowed to recognize values which
+               begin with a dot, e.g '.5' is treated as '0.5'
+    * added:   functions to the parser: gradtorad(grad), radtograd(rad), degtograd(deg),
+               degtograd(d,m,s), gradtodeg(grad)
+    * added:   a short form of multiplication
+               (without the '*' character) e.g. '5y'
+               (it's used only if the second parameter is a variable
+               or function)
+
+
+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

+<h1>Accuracy</h1>
+
+<p>
+TTCalc uses binary floating point numbers. It means that your input values are first
+converted to a binary representation and then the calculations are performed. After
+calculating the result is again converted from the binary to the decimal (you can
+select the input and output format on the display tab). You must remember that not
+all values can be converted from binary to decimal (and vice versa) without loosing
+accuracy. For example decimal '5' can be converted to binary '101' and the '101' is
+exactly equal decimal 5. But decimal '0.3' has not a good binary representation, it
+is '0.010011001100110011.....'. And when you put decimal '0.3' the calculations are
+performed on an approximate value and the result is only an approximation too.
+</p>
+
+<p>
+For example try to calculate: 0.204 - 0.34*0.80 + 0.068, you would expect that the
+result would be: 0 but TTCalc gives you: 3.15544362088404722164691426e-30 which is
+a good approximation to the real zero (look at e-30 part which means 10^(-30)).

 If you want to insert a value with a base (radix) 2 or 16 use the unary operator &amp; (for the base 2)
 or # (for the base 16).
 For example &amp;10=2 (decimal), #10=16 (decimal). When you're using these operators 
 then 'input' mode on the 'display' tab is ignored.
