CHANGELOG
@@ -1,21 +1,26 @@
|
||||
Version 0.8.6 (2009.10.25):
|
||||
* fixed: UInt::SetBitInWord(uint & value, uint bit) set 1 if the bit was
|
||||
equal 1 (should be set 2)
|
||||
this affected only no-asm parts - when macro TTMATH_NOASM was defined
|
||||
* fixed: UInt<value_size>::MulInt(uint ss2)
|
||||
there was a buffer overflow when value_size was equal 1
|
||||
* fixed: UInt::AddVector() and UInt::SubVector() didn't want to compile
|
||||
when macro TTMATH_NOASM was defined
|
||||
* fixed: Big::operator>> didn't correctly recognize values in scientific mode (with 'e' character)
|
||||
* fixed: Int::FromString(const tt_string & s, uint b = 10)
|
||||
didn't use 'b' (always was '10')
|
||||
* fixed: buffer overflow in Big::ToInt(Int<int_size> & result)
|
||||
* fixed: powering algorithm in:
|
||||
UInt::Pow(UInt<value_size> pow)
|
||||
Big::Pow(UInt<pow_size> pow)
|
||||
Big::PowUInt(Big<exp, man> pow)
|
||||
when 'pow' was sufficient large the algorithm returned carry
|
||||
but the result could have been calculated correctly
|
||||
Version 0.9.0 prerelease (2009.07.16):
|
||||
* added: support for wide characters (wchar_t)
|
||||
wide characters are used when macro TTMATH_USE_WCHAR is defined
|
||||
this macro is defined automatically when there is macro UNICODE or _UNICODE defined
|
||||
some types have been changed
|
||||
char -> tt_char
|
||||
std::string -> tt_string
|
||||
std::ostringstream -> tt_ostringstream
|
||||
std::ostream -> tt_ostream
|
||||
std::istream -> tt_istream
|
||||
normally tt_char is equal char but when you are using wide characters then tt_char will be wchar_t (and so on)
|
||||
(all typedef's are in ttmathtypes.h)
|
||||
* added: Big::IsInteger()
|
||||
returns true if the value is integer (without fraction)
|
||||
(NaN flag is not checked)
|
||||
* added: global Gamma() function
|
||||
* added: gamma() function to the parser
|
||||
* added: CGamma<ValueType> class
|
||||
is used with Gamma() and Factorial() in multithreaded environment
|
||||
* changed: Factorial() is using the Gamma() function now
|
||||
* removed: Parser<>::SetFactorialMax() method
|
||||
the factorial() is such a fast now that we don't need the method longer
|
||||
* removed: ErrorCode::err_too_big_factorial
|
||||
|
||||

What is the 'reference' error?
|

Some kind of methods use a reference as their argument to another object,

and the another object not always can be the same which is calling, e.g.
|
||||
Big<1,2> foo(10);
|

foo.Mul(foo); // this is incorrect

above method Mul is making something more with 'this' object and

'this' cannot be passed as the argument because the result will be undefined

|

macro TTMATH_REFERENCE_ASSERT helps us to solve the above problem

note! some methods can use 'this' object as the argument

for example this code is correct:

foo.Add(foo);

A small class used for reporting 'reference' errors

In the library is used macro TTMATH_REFERENCE_ASSERT which

|
||||
|
||||
What is the 'reference' error?
|
||||
Some kind of methods use a reference as their argument to another object,
|
||||
and the another object not always can be the same which is calling, e.g.
|
||||
Big<1,2> foo(10);
|
||||
foo.Mul(foo); // this is incorrect
|
||||
above method Mul is making something more with 'this' object and
|
||||
'this' cannot be passed as the argument because the result will be undefined
|
||||
|
||||
macro TTMATH_REFERENCE_ASSERT helps us to solve the above problem
|
||||
|
||||
note! some methods can use 'this' object as the argument
|
||||
for example this code is correct:
|
||||
UInt<2> foo(10);
|

foo.Add(foo);
