Hi all,
I'm seeing small bug in printf implementation.
May be a bug in newlib ??

Dealing with integers illustrates the matter more clearly. When
the decimal value is exactly 0.5, then printf should round to the

Thank you for your explanation. I didn't know, until now, that
rounding should be done to t

For what it's worth: My Sunblade 100 running Solaris 9 has
Solaris' /bin/printf and GNU's printf as /usr/local/bin/pr

I didn't know there were different rounding modes.
I thought everyone used so-called "unbiased rounding",
so I'm sorry for adding confusion.

Isn't this just a case of the Cygwin math library choosing "round to
even" and the MSVCRT/mingw library choosing "0.5 always

little digging:
1) cygwin strtod rounds to even, with about DECIMAL_DIG (==21) digits
precision, as recommended by 7.20.1.3 of WG14/N843. (It acts strange
when the rounding mode is not round to nearest, but since newlib
doesn't pro
