CHANGELOG

+Version 0.9.2 (2010.09.24):
+    * added:   Italian translation made by
+               Damiano Monaco <dmonax at gmail.com>
+    * added:   menu: edit->swap (ctrl+W)
+               swapping the input for the output edit
+
+    Changes from TTMath 0.9.2 relating to TTCalc:
+    * fixed:   Big::Add() sometimes incorrectly rounded the last bit from its mantissa
+    * fixed:   Big::ToString method
+               in some cases when in the output string the exponent should be equal zero
+               the method changes the exponent to one so the last digit from the mantissa
+               was lost
+   
+
+Version 0.9.1 (2010.02.07):
+    * 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)
+    * fixed:   added in the parser: operator's associativity
+               operator ^ (powering) is right-associative:
+               sample: 2^3^4 is equal 2^(3^4) and it is: 2.41e+24
+               previously was: 2^3^4 = (2^3)^4 = 4096
+    * changed: in Big::ToString() the base rounding is made only if the result value
+               would not be an integer, e.g. if the value is 1.999999999999 then
+               the base rounding will not be done - because as the result would be 2
+    * added:   IEEE 754 half-to-even rounding (bankers' rounding) to the following
+               floating point algorithms: Big::Add, Big::Sub, Big::Mul, Big::Div
+
+
 Version 0.9.0 (2009.11.25):
     * fixed:   when 'C' button was pressed, the cursor was not placed in the edit window
     * added:   Pad window - a multiline edit window
