Subject: fix float formatting of some exact halfway cases
|
|
|
|
in nearest rounding mode exact halfway cases were not following the
|
|
round to even rule if the rounding happened at a base 1000000000 digit
|
|
boundary of the internal representation and the previous digit was odd.
|
|
|
|
e.g. printf("%.0f", 1.5) printed 1 instead of 2.
