-Version 0.9.1 prerelease (2009.01.05):
+Version 0.9.1 (2009.02.07):
     * fixed:   the pad window didn't take into account following options (from display tab):
                grouping, input commas and parameter separators
-    * updated: chinese translation

+    Changes from TTMath 0.9.1 relating to TTCalc:
     * fixed:   the parser didn't use characters for changing the base (# and &)
                those characters were skipped
                (this bug was introduced in 0.9.0)
-    * added:   to Big::ToString() - additional rounding when conv.base_round is used
+    * fixed:   added in the parser: operator's associativity
-               if the value is not an integer we calculate how many valid digits there are
+               operator ^ (powering) is right-associative:
-               after the comma operator (in conv.base radix) and then we skipped the rest
+               sample: 2^3^4 is equal 2^(3^4) and it is: 2.41e+24
-               digits, after skipping the base-rounding is made
+               previously was: 2^3^4 = (2^3)^4 = 4096
-               this helps to print values which have some last clear bits in the mantissa
+    * changed: in Big::ToString() the base rounding is made only if the result value
-               consider this 32 bit value:
+               would not be an integer, e.g. if the value is 1.999999999999 then
-               (binary)0.00011100001010001111010111000000000
+               the base rounding will not be done - because as the result would be 2
-               which has mantissa equal: (binary)11100001010001111010111000000000 (32 bits)
+    * added:   IEEE 754 half-to-even rounding (bankers' rounding) to the following
-               previous the ToString() method gave: (decimal)0.10999999[...] 
+               floating point algorithms: Big::Add, Big::Sub, Big::Mul, Big::Div
-               now we have: (decimal)0.11
+
-    * added:   Parser::SetSmallToZero(bool zero) (default true)
-               if true then the parser changes small values into zero
-               small value means:
-               - if the mantissa of the value consists only of one, two or three set bits
-               - and these bits are next to each other
-               - and the exponent is smaller than about 2 times the number of bits from the mantissa
-               this helps to correctly calculate expressions such as: "0.80-3*0.34+0.22"
-               now the parser gives zero (previous there was a value very closed to zero)
 
 Version 0.9.0 (2009.11.25):
     * fixed:   when 'C' button was pressed, the cursor was not placed in the edit window
