| | | | | | | | | | | incorrect result with tcc: x.s.exp is declared as an unsigned bit-field, so that tcc considers that x.s.exp - 1023 is unsigned. However, since all the values of x.s.exp are representable in an int, according to the integer promotion rules, x.s.exp should be converted to an int, so that the subtraction is signed. So, this appears to be a bug in tcc. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@10443 280ebfd0-de03-0410-8827-d642c229c3f4

| | | | | | | | | | | In MPFR_RNDN (rounding to nearest), when |b| is the midpoint between the maximum number and 2^emax (the maximum number + 1 ulp) and c is small, the obtained result is an infinity (with overflow) instead of ± the maximum number (no overflow). The cause is that an overflow is generated too early (in the rounding code).
