Version 0.9.0 prerelease (2009.10.18):
Version 0.9.0 prerelease (2009.11.01):
* fixed: when 'C' button was pressed, the cursor was not put in the edit window
* added: Pad window - a multiline edit window
* added: Checking for update dialog box
* added: there are some new buttons on the standard tab
- (...) - the whole expression is surrounded by brackets
- 1/(...)
- ;
- % - a new percentage operator
- floor/ceil/min/max/sqrt/root/gamma
* added: some new options on display tab:
- grouping
- input decimal point
- parameters separated by
* changed: precision:
Medium - 512 mantissa, 64 exponent
Big - 1024 mantissa, 128 exponent
Changes from TTMath 0.9.0 prerelease relating to TTCalc:
* added: operator percentage
e.g. 1000-50%=1000-(1000*0,5)=500
e.g. 1000-50% = 1000-(1000*0,5) = 500
* added: function frac(x) - returns a value without the integer part
(only fraction remains)
* changed: algorithms in sqrt(x) and root(x ; n)
they were not too much accurate for some integers
e.g. Root(16;4) returned a value very closed to 2 but not exactly 2
Version 0.8.7 prerelease (2009.09.16):
* added: new language: Swedish

<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
result was 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)).
