Subject: [PATCH] signal.7: Better description for SIGFPE
Date: Tue, 24 Sep 2024 13:54:46 +0200	[thread overview]
Message-ID: <20240924115547.294466-1-vincent@vinc17.net> (raw)

SIGFPE has comment "Floating-point exception", which corresponds to
the FPE acronym. But this is misleading as this signal may also be
generated by an integer division by 0.

Change it to "Erroneous arithmetic operation" from POSIX:
https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/signal.h.html

Note: the GNU C Library manual says "fatal arithmetic error".
https://www.gnu.org/software/libc/manual/html_node/Program-Error-Signals.html
