Hello folks,

we have received a new BZ report for a different behaviour of Gawk when MPFR is used and when it is not. Reproducer script:

BEGIN {
  ROUNDMODE = "A"
  x = 2.21
  printf "%4.2f\n",x
  printf "%3.1f\n",x
  exit
}

$ gawk -f ./script
2.21

2.2

$ gawk -M -f ./script
2.21

2.3

The interesting discussion about this was also here - https://forums.fedoraforum.org/showthread.php?316207-Setting-gawk-ROUNDMODE&p=1798362#post1798362 :
"Hmm, looks like Gawk is just (unintentionally) doing with ROUNDMODE="A" what MPFR is doing with its MPFR_RNDA: it's rounding away from zero at all times, not just for ties."

Is this really a bug, or just user expecting something wrong from gawk?
