Subject: [PATCH 1/2] math: Make RATIONAL tristate
Date: Tue,  6 Jul 2021 12:09:44 +0200	[thread overview]
Message-ID: <20210706100945.3803694-2-geert@linux-m68k.org> (raw)
In-Reply-To: <20210706100945.3803694-1-geert@linux-m68k.org>

All but one symbols that select RATIONAL are tristate, but RATIONAL
itself is bool.  Change it to tristate, so the rational fractions
support code can be modular if no builtin code relies on it.
