From fe37ad15cd394af021af7a3e5ad11bad70af4bfd Mon Sep 17 00:00:00 2001 From: Jim Warner Date: Sun, 27 Apr 2014 00:00:00 -0500 Subject: [PATCH] top: avoid a 'nan' when the delay interval is very low The granularity of /proc/uptime is fixed at hundredths of a second. And, since we can cycle faster than that, we are exposed to 'nan' when calculating elapsed time. This commit will protect us from that outcome when the delay interval has been set to an extremely low value.
