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 prerelease relating to TTCalc:
|
||||
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
|
||||
if the value is not an integer we calculate how many valid digits there are
|
||||
after the comma operator (in conv.base radix) and then we skipped the rest
|
||||
digits, after skipping the base-rounding is made
|
||||
this helps to print values which have some last clear bits in the mantissa
|
||||
consider this 32 bit value:
|
||||
(binary)0.00011100001010001111010111000000000
|
||||
which has mantissa equal: (binary)11100001010001111010111000000000 (32 bits)
|
||||
previous the ToString() method gave: (decimal)0.10999999[...]
|
||||
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)
|
||||
* 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
