Unfortunately that version of groff's Texinfo manual corresponds to the most recent groff release, which is sadly 4½ years old: groff 1.22.4 of December 2018. There have been some changes to it since then: $ COLUMNS=72 git diff --stat 1.22.4 doc/groff.texi warning: refname '1.22.4' is ambiguous. doc/groff.texi | 20342 +++++++++++++++++++++++++---------------------- 1 file changed, 11020 insertions(+), 9322 deletions(-) Bertrand and I trying to get 1.23.0 finalized, but his availability is pretty limited. When it _does_ release, the copy of the manual at the GNU website will be updated. In the meantime, I recommend checking out my Dropbox account for much more up to date copies. At present there is a folder for 1.23.0.rc4, but in the parent is even more up-to-date documentation generated from groff Git HEAD. https://www.dropbox.com/sh/17ftu3z31couf07/AAC_9kq0ZA-Ra2ZhmZFWlLuva?dl=0 I think the current state of the manual is responsive to your questions; please check out the sections "Numeric Expressions" (pp. 79-82) and "Conditional Blocks" (pp. 165-167). Please advise me if the material seems incomplete, misleading, or unclear to you. Regards, Branden
