This section describes features and/or command-line options from
previous releases of gawk that either are not available in the
current version or are still supported but deprecated (meaning that
they will not be in a future release).
As of
gawk version 5.2,
the arbitrary precision arithmetic feature is “on parole.”
This feature is now being
supported by a volunteer in the development team and not by the primary
maintainer. If this situation changes, then the feature will be removed.
For more information see Arbitrary Precision Arithmetic is On Parole!.
