From d8cca5bed3b877655555930bc2f6f6f74503b455 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 4 Sep 2011 15:08:31 -0700 Subject: [PATCH] Save milli-units with variable precision Instead of always using three decimal digits, use 1-3 digits. But do use at least one, even for integer numbers, just because it makes it so much clearer that we're dealing with potential fractional values.
