Version 0.8.4 prerelease (2009.05.05):
Version 0.8.5 (2009.05.11):
* fixed: Big::Mod(x) didn't correctly return a carry
and the result was sometimes very big (even greater than x)
* fixed: global function Mod(x) didn't set an ErrorCode object
* fixed: global function Round() didn't test a carry
now it sets ErrorCode object
* changed: function Sin(x) to Sin(x, ErrorCode * err=0)
when x was very big the function returns zero
now it sets ErrorCode object to err_overflow
and the result is undefined
the same is to Cos() function
* changed: PrepareSin(x) is using Big::Mod() now when reducing 2PI period
should be a little accurate especially on a very big 'x'
Version 0.8.4 (2009.05.08):
* fixed: UInt::DivInt() didn't check whether the divisor is zero
there was a hardware interruption when the divisor was zero
(now the method returns one)

(like "m" (mask) constraints in Rcl2 and Rcr2) have also gone away,
now the library works well with -O2 and -O3 and the asm code
is a little faster
* added: UInt::PrintLog(const char * msg, std::ostream & output)
* added: UInt::PrintLog(const char * msg, std::ostream & output)
used (for debugging purposes) by macro TTMATH_LOG(msg)
(it is used in nearly all methods in UInt class)
* added: macro TTMATH_DEBUG_LOG: when defined then TTMATH_LOG()

(it's used when macro TTMATH_NOASM is defined)
The third form can be used on x86 and x86_64 as well and
on other platforms with a little effort.
(Temporarily I left there some '#ifdef's for debugging.)

to do is to use 'include' directive of the preprocessor. How big the
values can be is set directly in the source code by the programmer.
