Version 0.9.1 prerelease (2009.12.05):
Version 0.9.1 prerelease (2009.12.06):
* 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: IEEE 754 half-to-even rounding (bankers' rounding) to the following
floating point algorithms:
Big::Add
Big::Sub
Big::Mul
Big::Div
* 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
